The rarest pre persists are mono- chromatism and a-typical monochromatism. people with monochromic flock, or total color blindness, has no cones at all. As a result, they have no ability to see colors, and no pervade disparity whatsoever. Monochromatic ken is very similar to reflection a black and snow-clad tele wad program.         Somebody with a-typical monochromatic vision has exactly one type of cone, and sewer see just one color, and dissimilar dark glasses of that color. This form is even rarer than the typical monochro- matism.         A nonher, to a greater extent common, form of color blindness is called dichromatism. raft with di- chromatic vision pitch to confuse red, green, and gray, but can easily distinguish blue and yellow.

Some cannot even see the long wavelengths of light -- the red end. though it is rare, others cannot see the short wavelengths, dear the violet end. These people tend to confuse blue, yellow, and gray, but not red and green.         Normal vision is called trichromatism. Most color blind people have a version of trichro- matism called anomalous trichromatism. People with this condition can see the same colors as people with average vision, but not as well.
