Monochromatic vision is very similar to observance a black and white television program.         Somebody with a-typical monochromatic vision has exactly one type of cone, and can see just one color, and various dark glasses of that color. This form is counterbalance rarer than the typical monochro- matism.         A nonher, more common, form of color blindness is called dichromatism. People with di- chromatic vision tend to shake off red, green, and gray, except can easily distinguish blue and yellow. Some cannot even see the hourlong wavelengths of light -- the red end. Though it is rare, others cannot see the short wavelengths, heartfelt 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 adaption of trichro- matism called anomalous trichromatism.
