Color blindness affects roughly 8 percent of males and less than 1 percent of females worldwide. There are three types of color blindness: deuteranopia(green color blindness), protanopia(red color blindness), and tritanopia(blue color blindness). Even though a person with one type of color blindness is insensitive to one color, other colors composed of that color (orange is yellow and red, purple is red and blue, etc.) may get confused. For example, I don't usually see the red in purple, so it looks blue to me. That is a brief description about color blindness.
