What are some physical symptoms of this disease?

The obvious symptom of being color deficient is lacking the wavelength perception (which I mentioned in an earlier post) to see some shades of color. According to WebMd, there are three kinds of symptoms of color blindness. These are:  1)being able to see many colors and you might not even know you have a problem  2) being able to see only a few shades of color and 3) in rare cases, seeing in monochrome.
