COLOR BLINDNESS
Color blindness is used to describe mild to severe difficulties with identifying various colors and shades of colors. Color blindness is a result of a lack of one or more of the color receptors which are red, blue and green. Most color difficulties are with red and/or green. About 4% of males have a color defect; however, less than 1% of females have this trait. The photo represents a simple example of a color plate test.
