Color blindness is genetic and so is present at birth. There are three types of color-blindness, also known as color vision defect. The first is red-green color blindness and is the most common. The second is blue-yellow and the third is complete lack of color vision. For each type of color blindness, rather than seeing the colors as they are, one would see varying degrees of intensity of the particular color, or not see the color at all, resulting in shades of brown or grey. The gene for color blindness is carried on the X chromosome, therefore more males than females are affected.
