It is a wide known fact that colors can manipulate us.

There is a whole science that studies colors, the way we people perceive them, and the psychological effects they have on us.

It is called colorimetry, or simply color science. In this article, we will talk about the emotions that colors make us feel and how we perceive them.

Have you ever noticed how specific colors make you feel specific things?

Like when you look at the green you feel tranquil and calm?

The reason behind this fact is that we relate green to nature’s colors about leaves, plants, and grass.

Haven’t you asked yourself why traffic lights are specially working with these three colors: green, yellow and red?

It is all coming down to color phycology.

Why colors have such a great impact on us?

While animals have greater hearing and smelling senses, night vision, and even electricity waves perception, we humans rely too much on our eyes to understand the world around us.

Colors may be powerful tools to bring up memories, make someone feel in a specific way or call to action.

Without a doubt, the explanation about this is coded deep in our human beings.

In nature, there are two groups of colors – warm and cold.

Most people associate warm colors with the day, springtime and summer.

Such colors are all the shades that come out of yellow, red, and orange.

And the cold spectrum reminds us of the night and winter.

Their colors are purple and violet, blue, and grey, plus their many shades.

Thus, warm colors make us feel lively, full of energy, while on the other hand, cold colors remind us of calmness.

How different colors manipulate us?

Black and white

White is good and black is bad’ – this is how most people understand these two colors nowadays.

Black- mostly like the color of all bad things.

It is frequently connected with occasions that people hate.

Like mourning, death, and depression.

But also with power and strength.

According to science, this is the color that absorbs the whole spectrum of the white light.

Nonetheless, being a color with such a reputation, it is still the most searched for in clothing, both by men and women.

This may be because when worn on clothes, black hints of boldness, self-confidence, and formality.

On the other hand, white is often linked with purity and god-like, angelic powers.

Usually, brides wear white and used in hospitals.

Usually, you could spot that designers rely on this color to make a room seem larger and more spacious.

Warm colors

Red

When do you see red?

You can see it on traffic lights because it attracts attention and warns about the danger.

Red is an intense, dynamic color that may invoke many emotions.

Not only does it bring up a reminder of love, but also anger.

Red is one of the most emotional colors of all.

Moreover, red is considered to boost up productivity and creativity.

Yellow

Yellow brings attention, therefore all labels of great importance and signs are colored in yellow.

You can easily spot it while driving – on the traffic lights, street signs, and billboards.

Yellow is the very first color that babies perceive after they are born.

It establishes a warm atmosphere with a pinch of something fun.

Orange

Most of people think of an orange as a happy color.

It is warm and inspiring.

This color tends to make people proactive and full of energy.

Besides, orange reminds us of comfortable autumn evenings and pumpkin treats.

Pink

Usually, when we think of ‘pink’ something girlish and feminine comes to our minds.

Pink is linked to romance and love, compassion and sensitivity.

There is an international day of the Pink Shirt, celebrated every year, that symbolizes the intolerance of bullying and supports kindness among people.

Brown

Brown is a warm color associated with nature, for it is seen in the earth, on trees and plants, etc.

It is a neutral color that rarely brings up any strong emotions.

In fashion, brown varies from pale beige to deep dark brown.

Despite the shades, though, brown is seen as a boring color when it comes to clothing.

Cold colors

Blue

Blue is a sad color, also it is cool and lonely.

In nature, we connect blue to winter and coldness.

This is the reason we perceive it that way.

Still, it is also a calm and stable color.

Many people chose it for their bedrooms, especially the male half.

In the same way that women prefer pink and red, men prefer blue and its different shades.

Another interesting fact about blue is that people whose job is to be in a blue room seem to be more productive and their thoughts flow straight, they tend to not get easily distracted.

The light your computer or smartphone display emitters is cold blue light.

Blue light is in contrast to the light that our eyes get naturally from the sun.

Therefore blue light leads to damage to your eyes.

Read more on blue light and why it is damaging your eyes, and check out Iris – a reliable blue light-blocking software.

Purple

This is an exotic color.

It cannot be found easily in nature, therefore it is a combination of red and blue – one warm and one cold color.

In history, it was associated with royal families due to the fact that it was expensive to dye and find such fabrics.

Nowadays it is commonly seen as a spiritual and peculiar color that many love because of its attractiveness.

Green

What is the first thing you think about green?

Of course, it is about nature. When we think of it, it brings us calmness and relaxes.

Our thoughts fly away to quiet forests and sunny meadows.

This is the reason why color therapies include green.

Nature is green, but money, healing, and luck are too.

Apart from the association above, many see green in different ways.

Therefore green is just like red one of the most temperamental colors.

Conclusion

People perceive and see the world through colors.

Companies use the colors through marketing to draw up clients.

Anyway, they help us understand different situations in our life and provide us with the ability to express ourselves.

All of this only because our minds are used to colors since birth.

Marketing and advertising 

Color and color vision are one of the most important, key aspects in our lives when it comes to living and perceiving the world as we do.

We as human beings are visual creatures, meaning about 90% of the information we take in from the surrounding environment is in the form of visual input through our eyes.

Color vision was, is and will always be important to us.

It was a key evolutionary trait that our ancestors developed that helped them survive, thrive and spread around the world.

It affects us deeply and the majority of the time subconsciously without us even realizing it.

In today’s capitalist, saturated market, no one knows this better than brands and companies themselves.

Striving to attract attention, fighting the silent battle for the customer’s dollar every day.

Brands and companies have developed a series of key tactics to sell their products and services.

They use the right colors in their logos, marketing and advertising to invoke specific feelings in their target customers.

Color science was definitely not invented by brands and has naturally existed long before companies.

Putting the information gathered and researched to use in the marketing and sales field is definitely a specific trait of the 20th and 21st-century company.

The effects of color on human subconsciousness have been documented in detail by various scientists over the years with results showing mostly similar effects of certain colors on people and their psyche.

Below listed are some basic colors we see in the environment and in our everyday life and the documented subconscious effects they have been reported to have on the human mind:

Red

The color is widely recognized as the color of passion, romance and love, but has also widely been reported to be associated with danger, excitement and urgency.

Usually most widely used by stores, brands and companies when they want to attract attention to their products and create a sense of urgency, during sales for example.

Think of the STOP sign and the red signal on traffic lights.

Green

Being the color of grass, trees and nature in general, naturally, the color is associated with the environment, relaxation, safety, health, life, healing, etc.

Interestingly enough, because of the nature of the world and the economy, we have created, one of the things the human brain most frequently connects green to is money.

Blue

Associated mostly with peace, stability, calmness and tranquility.

It’s also the color most widely used in social media design and layout, the how and why of which are a topic for another article (spoiler alert: blue can be dangerous for your eyesight and attention span).

Yellow

Associated with joy, energy, cheerfulness and warmth. Like red, it may also be used to create a sense of urgency, caution and emergency.

Gray

Think of all the buildings surrounding us, think of the concrete jungle – gray is most widely connected to stability, security, strength of character, authority and maturity.

Black and White

For colors that are technically not considered colors at all, our minds seem to connect black and white to various different things.

Sophistication, power, mystery, formality, evil and death for black..

..and freshness, hope, light, goodness, purity, cleanliness and simplicity for white, just to name a few.

Of course, those are just a few of the colors companies use in their logos, marketing and advertising.

Going into full detail about every color and how it affects us would take hundreds of articles and following the ways companies carefully craft their logos.

From design to colors and even color hues would be practically impossible as those are industry secrets.

The negative effects of color on health

Naturally, we need color. Color in life is what defines our sight and makes our world vivid and vibrant.

Should we be afraid of too much color though?

Way too much of a certain color can have a negative impact on a person’s health.

It has been reported that “overdosing” on certain colors like red and yellow, which induce feelings of urgency and excitement can have a negative impact on our health, resulting in high blood pressure and anxiety.

On the other hand “overdosing” on blue (coincidentally used in a lot in social media design and layout as a primary color) can make us feel too calm and relaxed and lose track of time.

Endlessly scrolling as time passes, subconsciously dozing off and ignoring the world around us.

Additionally, blue is one of the colors the retina cannot block from causing damage to our eyes.

As red light gets blocked, blue light can pass right through and with prolonged use of blue light-emitting technology.

Blue light can cause health issues connected to sore eyes, migraines and headaches.

The takeaway

As already mentioned, going into full detail about every color in life and the way it can impact us negatively or positively would take a lot of time.

But in today’s world where we’re constantly bombarded with advertisements and logos anywhere we go.

Being educated on the how and why of advertising, marketing and color science can be beneficial to us.

We can stop ourselves from making impulse purchases based on subconscious decisions we make without even realizing it and prevent the negative effects from them.

Most importantly, however, knowing color in life and the way colors influence us can help us reduce exposure to an excess of certain colors, preventing health issues.

We ourselves love color, but like everything we know, it should be used in moderation.

The software we developed helps you do just that! – controlling how much and which colors you see every day from your computer screen, helping you regain control.

 Review the different free and paid options the Iris software offers, pick the one that suits your needs best.

Say goodbye to those constant headaches and start improving your productivity and quality of life today.

Blue light Effects

The Complete Guide to Color Therapy

Blue Light from Electronics

The post The science of color in life appeared first on 💡👨‍💻 Iris - Software for Eye protection, Health and Productivity 🛌👀.

Chromotherapy is a system of alternative medicine based on the use of projected different colored light.

Otherwise known as just color therapy, it’s an exciting new addition to your local spa.

Antiquity

However, color therapy is not something new.

It has been used in medicinal practices over 2000 years ago in ancient Egypt and China.

Of course, back then people had no understanding of the science behind light and different colors, but they certainly believed in their healing properties.

Ancient Egyptians considered chromotherapy as part of their mythology and constructed various healing rooms with different colored crystals, oil, minerals, and remedies.

Chromotherapy was also often combined with aromatherapy.

In ancient India began the view that still stands to this day in some monasteries that sunlight is essential to healing and well-being.

In ancient Greece began the rise of the physical prominence of color that still dominates our lives in modern times.

The ruins of statues and temples that we see today as white were originally painted in striking bright colors.

The ancient Greeks wore vivid garments and used many oils, crystals, dyes and ointments (that probably also came from Egypt) in the belief that colors affect our physical and mental state.

In the early Middle Ages, many philosophers created color charts and started associating different colors with different parts of the human body and different diseases.

Modern times

The modern understanding of the light spectrum began in 1672 with the experiments of Isaac Newton on the light spectrum.

He discovered that white light splits into the different colors of the spectrum when passing through a prism.

The belief that light and color can be used as a healing technique continued through the centuries after.

In the 19th century, there were many books published that explore the effects of light on animals and plants with various diseases.

Some avid researchers even performed experiments on people to further their claims on light therapy.

In the 20th century, many people began to try and explain why different colors of light had certain effects on particular parts of the human body and others didn’t.

By this time scientists had already done some research on the light spectrum and studying the wavelengths of different colors.

It turns out color is not just light but also energy.

This way by receiving energy the brain interprets the wavelength of the light and makes our perception of color a physical and sensory experience.

We already know about the effects non-visible light has on our bodies so naturally, visible light should also have some kind of action on us.

Perception

It’s a common misconception that we perceive light only with our eyes.

Light is just a wave and can enter through our skin and pass right through our bodies.

The longer the wavelength of light the deeper it can come through the skin.

All this is why people have and continue to believe that diverse color vibrations can stimulate different moods and reactions in humans and even have an effect on the way our bodies grow and heal.

Color symbolism has also been used in different cultures throughout the world.

For example, think of a specific country like Italy or China－you immediately associate them with some kind of color.

This is also true for traditions like wedding attire, rituals, and folklore, the color of different foods around the world.

In modern times colors are an important part in marketing and advertising.

Subconsciously practically everyone believes that different colors somehow affect our mindset and way of thinking.

But how exactly? Should we believe all of this?

Is it more likely for me to buy a hamburger if the logo of the restaurant was yellow rather than violet?

Can I be healed from lung cancer if I’m exposed to green light? Can we be sure and how much exactly is plausible in the different color meanings?

The spectrum

Warm colors

Red

Red is a color associated with energy and the bloodstream.

It’s considered to stimulate cell growth and metabolism.

It’s also the healthiest color for our eyes. In some cultures, it’s considered as the color of pureness and marriage.

Red along with orange is also an abundant color in fruits and stimulates our appetite.

Orange

Orange is warm and cheerful, it’s considered the colors of happiness.

You’ve also probably wondered which was named first the color orange or the fruit?

Well, whatever it is it’s no coincidence because oranges have Vitamin C which is very important when fighting the flu or a regular Thursday cough.

Yellow

Yellow is often associated with mental health.

It’s a color that stimulates interest and increases awareness.

It’s also related to the ability to perceive and understand.

Yellow is a very popular color in marketing too.

That’s mostly because we see the Sun as yellow we consider it to be the brightest and happiest color.

Cold colors

Green

The Sun gives off light in the whole spectrum but it’s maximum is in green.

So it’s no coincidence that green has been considered by many as the most healing color that starts a process of throughout restoration and ‘makes everything feel good’.

Green is also the color of nature－grass, trees, leaves.

Being in the middle of the visible spectrum green is considered to bring balance in every aspect of life.

Green is also the color of money. ?

Blue

Blue light is the most dangerous type of light.

We’ve discussed its effects on health and the human eye many times.

You can check out our other informative articles “Blue light – learn the fact and fiction behind this modern threat” and “How blue light destroyed our sleep“.

Don’t forget however that not all blue light is harmful. Blue is the color of the sky!

It helps us know when we should sleep and wake up.

Regulates our circadian rhythm and keeps us on track.

Blue is also the color of many social media as it’s considered as a color connected to communication and speech.

Violet

Violet is a color often associated with power, authority and wisdom. It also stimulates creativity.

In the spectrum, violet is the last color before light switches into the dangerous short wavelengths.

Although violet is associated with injury it has been used to treat inflammatory issues, cramps and epilepsy.

Non-spectral colors

You’ve probably looked at a rainbow once or twice in your life and wondered “Where is brown?”.

That shouldn’t worry you at all. The human eye can perceive 7 MILLION colors!

What would that rainbow look like?

Colors that we see in our everyday life but not in the light spectrum are colors like white, gray, black, brown, pink, gold, silver and the so-called impossible colors.

Take a look at this fun picture that can show you some impossible colors:

So why are these colors not in the spectrum?

Well, white is a combination of all wavelengths in the visible spectrum, and black is the lack thereof.

Brown is a mix of a primary color and its complementary (meaning the color opposite it on the color wheel)

So if you mix yellow and purple－tada! You get brown.

Metallic colors, like gold, silver and platinum, on the other hand, have a characteristic that makes them what they are－shiny.

The shiny effect is due to the material’s brightness varying with the surface angle.

That’s how you get metallic colors.

Everybody’s favorite baby girl go-to color pink is just a mixture of red and white.

The more white you add the lighter pink you get.

Remember white was a mixture of all spectrum colors and then you add some red－isn’t pink the funkiest color?

Grey however you can make in various different ways. By mixing black and white. By mixing the primary colors.

By adding a little white to that primary mix. By mixing primary with a complementary color (and not getting brown).

What is the effect of all these kooky colors?

White has always been associated with purity and safety, and black with darkness and fear.

Brown is one of the nature colors, reminds you of tree bark and musty smells.

Metallic colors give us a sense of a new car or a fancy restaurant. Gold is after all a symbol of wealth.

And pink even in the 21st century is still considered a girly color (can we not with the prejudice?).

All of these are colors that you should be careful about how you incorporate in your daily life.

For the love of all good things don’t make your bathroom out of gold or paint your porch a bright neon pink!

Scientific validation

All of this is nice and everything but how much scientific recognition does all this have?

In these modern times if something regarding our health cannot be backed up by science it’s considered quackery and pseudoscience, no matter how many people actually believe in it.

In recent times color therapy is a huge business in the spa industry.

Verified or not it’s used to treat various disorders and diseases not only with the physical body but it also claims it can heal the soul.

Some hardcore supporters delve into claims of chakras and the electromagnetic recharge of the aura.

More down-to-earth users of color therapy believe it’s only a way to help you relax and unwind after a hard day or cope better after an injury.

Throughout the years color therapy has been used to treat inflammation, pain, open wound healing, burns, scars, back pain, sore muscles, jet lag, seasonal affective disorder (SAD) and many mental health issues like depression and anxiety.

Some people even believe it to have anti-aging properties, others are using it to treat violence and aggressive behavior.

Light therapy can also help with sleep disorders like insomnia, and help with work productivity.

This is very useful in northern countries where there is less light from the Sun on a daily basis.

None of these effects have actually been 100% confirmed by scientific experiments despite there being many attempts.

One study conducted on a certain kind of jellyfish showed that their primitive eye receptors send specific neural signals depending on the type of light shone upon them.

Read more about this study in our article about the evolution of eyes – “The eyes: from ancient jellyfish to modern humans“.

There are also many inconsistencies as to which color you should use for what.

Despite color therapy having many signs of being a pseudoscience, people are still participating in it.

There are many shared opinions on the internet of people’s stories on how colored light therapy has helped them in some way.

However, the main consensus in the science circle is that color therapy cannot treat serious diseases and can only help in placebo-type relaxation and perhaps some mental related issues－but it’s not a guaranteed treatment.

Conclusion

In conclusion, if color therapy helps you feel better, like a cold beer on a summer day, or a hot tea on a winter morning, then use it as you wish.

But remember－don’t let it replace a visit to the doctor.

Blue light filters remove (or at least partly) the blue light, which alters the colors

So when you are creating something with flux on, you will notice that the moment you turn it on or send it to somebody else the colors will look different

Of course, you can turn it off every time you start working but that’s just annoying

It would be nice to be able to do that automatically, wouldn’t it?

Well, there’s a way.

You can do that using Iris

It has a feature called Color Pausers and it will automatically stop altering colors when you are working with any program that you add

You can find more info on it here:

The post As a designer, what are the benefits of using F.lux? appeared first on 💡👨‍💻 Iris - Software for Eye protection, Health and Productivity 🛌👀.

In the late 1920s William David Wright and John Guild independently conducted a series of color matching experiments that mapped out all the colors the average human (meaning the average of the humans in the experiments) can see. In 1931 color scientists used the results of the Wright and Guild experiments to create the 1931 CIE XYZ color space (“XYZ” for short).

Visualizing XYZ

To visualize XYZ, think of a three-dimensional cartesian coordinate system (high school algebra) with axes labelled X, Y, and Z. In the XYZ color space, Y corresponds to relative luminance; Y also carries color information related to the eye’s “M” (yellow-green) cone response. X and Z carry additional information about how the cones in the human eye respond to light waves of varying frequencies.

Real colors and imaginary colors

Theoretically, the XYZ axes go off to infinity in both the positive and negative direction. However, not every set of coordinates in XYZ space corresponds to a color that the average human can see. XYZ coordinates that are outside the locus of colors mapped by the color matching experiments that led to the creation of the XYZ color space are called imaginary colors. XYZ coordinates that are inside the locus of colors mapped by the color matching experiments are called real colors.

Colors that weren’t measured

Not every being sees color exactly like the hypothetical average human. For example, birds, bees, dogs, and humans with nonstandard color perception don’t see the same colors in the same way as the average human. However, for purposes of the digital darkroom, the colors that are seen by any being with non-standard color perception are neither real nor imaginary. Here’s why:

As mentioned in the first section of this article, light waves of different frequencies are out there in the world, but color happens in the eye and brain. One could do (and I’m sure color scientists have done) color matching experiments with human tetrachromats, with color-blind humans, and perhaps even with birds, bees, dogs, and etc. But the resulting “tetrachromat-XYZ” color space (or “color-blind-XYZ” color space, or “bird-XYZ” color space) wouldn’t be the same as the “average humans only” 1931 CIE XYZ color space. These alternative color spaces would have their own sets of real and imaginary colors.

To summarize, if a flower reflects it (“it” being that complex phenomenon we call light) and a bee sees it, of course it’s real for the bee. And if a painting reflects it and a human tetrachromat sees it, it’s real for the tetrachromat. But as far as the 1931 CIE XYZ color space that we use in the digital darkroom is concerned, these “nonstandard color perception” colors aren’t real and aren’t imaginary, rather they simply weren’t measured during the color matching experiments that led to the creation of the XYZ color space.

1931 CIE XYZ

The CIE 1931 color spaces were the first defined quantitative links between physical pure colors (i.e. wavelengths) in the electromagnetic visible spectrum, and physiological perceived colors in human color vision.

The mathematical relationships that define these color spaces are essential tools for color management, important when dealing with color inks, illuminated displays, and recording devices such as digital cameras.

The XYZ color space is the basis of everything that relates to color in a color-managed image editing application.

On the one hand, light comes from the sun or other radiant sources, and is refracted by mediums (water, the atmosphere, glass) and diffusely or specularly reflected by surfaces.

On the other hand, color isn’t out there in the world in the same tangible way that light is. Rather color is part of how we sense the world around us.

Light enters the eyes, is processed by light receptors (cones and rods), and sent via the optic nerves to the brain for further processing and interpretation.

Light varies in wavelengths, which our eyes and brain interpret as varying colors, and also in intensity.

So our perception of color is composed of both intensity information and chromaticity information.

The naming of colors carries one out of the narrow realm of color perception, and into the larger realm of cultural and linguistic interpretation and classification of color, and thence into even larger philosophical, aesthetic, theological, and metaphysical considerations.

The human eye is an amazing machine. Through tiny cells called cones, our eyes are able to see about 10 million different colors. But not all colors are created equal, and some are just too difficult to look at as they can cause headaches, high blood pressure, and eye strain. With the increase in time spent in front of our digital devices – six to nine hours per day on average – the colors and even the fonts we stare at on our digital screens can become sights for sore eyes.

The Impact of Color and Fonts on the Eyes

Bright colors in particular can be harsh on our eyes – but they also draw our attention. Think about the color yellow. In lighter shades, yellow is comforting and cheerful. But when the brightness is cranked up, yellow can be a stimulant on the eyes. Studies show that babies cry more often in yellow rooms and couples tend to fight more in rooms with yellow paint. However, given its ranking as the most visible of all the colors, yellow is a great color to use when you need to grab attention. This explains the use of bright yellow on warning signs.

Different fonts can play tricks on our eyes too. Even though Times New Roman is a common default font in many computer programs, this font can actually hurt your eyes. The tiny tails on the end of each letter, called serifs, will force you to stare longer in order to recognize a word. This can lead to eye fatigue. Luckily there are fonts, such as Arial and Verdana, without serifs (sans-serifs), that have more space between each letter and are easier to read from farther away.

How to Stop Eye Strain from Harsh Colors and Fonts

It’s recommended that we stretch before a work-out to ensure we don’t strain our muscles, but have you stopped to think about the strain you put on your eye muscles everyday as you stare at your computer, television, phone, and other devices? You’ve most likely felt the effects of digital eye strain and computer vision syndrome – headaches, dryeyes, blurred vision, or even a sore neck – but what can you do to stop this pain? An easy way to combat eye strain is to simply adjust a few settings on your computer:

• Change the brightness setting – Match the brightness of your monitor to your surrounding workstation. To test this, look at the white background of this webpage. If it looks like a light source, your monitor is too bright. On the other hand, if it seems dull and gray, it may be too dark.
• Adjust text size and contrast – Text should be three times the smallest size you can read from a normal viewing position, which is about 20-30 inches from your monitor. As for contrast, black print on a white background is usually the best combination for comfortable reading.
• Stick with sans-serif fonts – As mentioned earlier, fonts without serifs, such as Arial, are much easier on the eyes.
• Increase browser display size – With the increase in wide-screen computer displays, websites are often shown as a column with empty margins. To increase the webpage so it fits your monitor, hold down the Control key and scroll up with your mouse. If you have a Mac, increase the browser window by pressing Command and + until you reach the size that looks best for you.
