Color is so much more than meets the eye. Color impacts our moods, stimulates our minds and influences how we feel about products and the companies that make them. Color influences how we experience the world around us.

But what, exactly, is color?

The Science Behind Color

In the simplest terms, color is light, a form of energy.

All electromagnetic energy is light from the sun and the majority of it travels in wavelengths in the infrared, visible and ultraviolent parts of the electromagnetic spectrums.

What we see as colors are actually wavelengths that are roughly 380 to 700 nanometers.  We call this range the visible light spectrum because it can be seen by the human eye (although some people can see further into the outer edges of this range than others).

Most humans can see a broad array of colors but in reality, what we see is only a tiny fraction of the colors that exist across the spectrum; other wavelengths are too large, too small or have too much energy for the human eye to perceive or comprehend.

A perfect illustration of this is how we experience a rainbow, formed when light enters water droplets where it is reflected and refracted.

Rainbows are actually made up of millions of colors, but the human eye can only see seven—red, orange, yellow, green, blue, indigo and violet.

How Businesses Harness Color

While the science behind color is complex, we don’t need to fully grasp it to appreciate the beauty of color or realize the strong influence that it has on the human mind.

Companies understand how to harness the power of color to make us feel a certain way about their products and their brands.

Time and time again, research has shown that color is among the most important factors in purchasing decisions.

  • 75% of snap decisions about a consumer product is based on product packaging or product color.
  • For more than than 60% of consumers, color is a major factor in making a vehicle purchase

Here are a few facts about some of our favorite hues and why businesses incorporate them into their branding, marketing and messaging.


As the most radiant color, yellow captures our attention quicker than every other color on the spectrum.
