This post will look at the actual definition of color according to the web.

Dictionary.com:

“the quality of an object or substance with respect to light reflected by the object, usually determined visually by measurement of hue, saturation, and brightness of the reflected light; saturation or chroma; hue.”

webexhibits:

“We perceive color just as we perceive taste. When we eat, our taste buds sense four attributes: sweet, salty, sour and bitter. Similarly, when we look at a scene, our visual nerves register color in terms of the attributes of color: the amount of green-or-red; the amount of blue-or-yellow; and the brightness.”

Online Learning Haven:

“The entire electromagnetic spectrum is made up of ultraviolet, visible light, and infrared. The human eye can only see the light sector of the spectrum. That is Red, Orange, Yellow, Green, Blue, Indigo and Violet. (ROY G BIV is how I was taught to remember it in school). These are also the colors you see in a rainbow after a rainstorm.
Visible Color

Color is the thing we perhaps notice most about light in the world around us. But why we see colors the way we do all has to do with light. The reason something appears to be the color that does is that the object is absorbing all the other colors of light except the ones we see, which are reflected back to our eyes. If something absorbs all the colors, it appears black, if it reflects everything, it appears white. Color comes from what is called the visible spectrum of light. Scientists measure the wavelengths of light in this spectrum in nanometers or billionths of a meter. Red has the longest wavelength, and violet has the shortest. So, what color we see depends on the wavelength of the light we absorb into our eyes. The primary colors are red, green, and blue, from these colors, every other color can be made.”

RGBWorld:

“Color is all around us. It is a sensation that adds excitement and emotion to our lives. Everything from the cloths we wear, to the pictures we paint revolves around color. Without color; the world (especially RGB World) would be a much less beautiful place. Color can also be used to describe emotions; we can be red hot, feeling blue, or be green with envy.

In order to understand color we need a brief overview of light. Without light, there would be no color, and hence no RGB World. Thank God for light!

Light is made up of energy waves which are grouped together in what is called a spectrum. Light that appears white to us, such as light from the sun, is actually composed of many colors. The wavelengths of light are not colored, but produce the sensation of color.”
