What is the range of colors?
The human eye sees color over wavelengths ranging roughly from 400 nanometers (violet) to 700 nanometers (red). Light from 400–700 nanometers (nm) is called visible light, or the visible spectrum because humans can see it.
What color is associated with value?
Orange is Associated with Good Value
People associate the color orange with a good value.
Why do color values range from 0 to 255?
Each of the red, green and blue light levels is encoded as a number in the range 0.. 255, with 0 meaning zero light and 255 meaning maximum light. So for example (red=255, green=100, blue=0) is a color where red is maximum, green is medium, and blue is not present at all, resulting in a shade of orange.
