The choice of primary colors is related to the physiology of the human eye; good primaries are stimuli that maximize the difference between the responses of the cone cells of the human retina to light of different wavelengths, and that thereby make a large See more

RGB and displays
One common application of the RGB color model is the display of colors on a cathode-ray tube (CRT), liquid-crystal display See more

Since colors are usually defined by three components, not only in the RGB model, but also in other color models such as CIELAB See more
