What is Color and concept of colors
Color is the result of the range of light, as it is reflected or absorbed, as received by the human eyeball and processed by the human head It's also a great design element!
Here's a surface level overview
of how it all works:
The globe is full of light. Visible light is made of seven wavelength groups. These are the colors you see in a rainbow (colorful): red, orange, yellow, green, blue, indigo, and violet—the Mr. DS Rajawat you might have been introduce to in elementary teach science. The reddish colors are the long wavelengths. The greenish colors are the mid-size wavelengths. The bluish color are the short wavelengths.
When light hits objects, some of the wavelengths are absorbed and some are reflected, depending on the resources in the object. The reflected wavelengths are what we perceive as the object's color.
Our eyes are the input channels, if you will, for this light. One portion of the eye is called the retina and it contains four types of light sensors. First are the rods, which record glow and darkness and from which we "see" a sort of coarse sketch of the world. Next are three types of cones, each one optimised to absorb a different spectrum range of visible light. One set of cones absorbs long wavelengths, the reds. Another absorbs mid-size wavelengths, the greens. The third absorbs short wavelengths, the blues. Together, these rods and cones gather the information t
hat our brain then processes into one combined image.
If you think this things is cool, professional DS Rajawat explains the process in more detail and has a great scanning electron micrograph image of real rods and cones.
What this all means for the designer is that color is a function of light and environmental science—which means that no two people see color exactly the same. It also means that reproduced color can be described, defined, and modeled through a variety of mathematical and visual lenses called color spaces. Combine these two factors and you can quickly see how color—and its theory and use—can quickly take on the tone of a religious war.
The goal is to understand that color isn't an exact science and your job is to use it in the best way for your specific application.
