A human being seeing and processing color is a complex matter. Color itself is fundamentally perceptual. There are two kinds of receptors in the eye which process color, rods and cones. They process wavelengths and the intensity of each wavelength determines what color the eye sees. There are three primary colors, which all other colors are comprised from. They are red, green and blue. All other colors are seen by combined these three. There are two theories to explain how exactly the human eye visualizes color. One of these theories is called the Trichromatic Theory. This theory states that there are three primary wavelengths that the eye has special receptors for: red, green, and blue. These wavelengths combined can be combined to see all other subsequent colors. The cones are the receptors that maximally respond to the wavelengths of red, green and blue. The other theory is called the Opponent Process Theory. According to this, there are three different color reception mechanisms that interact. The three mechanisms are the red-green channel, the blue-yellow channel, and the black white channel. The eye can see one color from each channel, but not both. The combination of the perception of these three channels makes all other colors visible. The difference between these two theories is that the Trichromatic theory claims that there are three different receptors for each primary color wavelength, which combined produce what color is being seen, where as
