Color blindness, also known as color vision deficiency, is the decreased ability to see color or differences in color.
Color blindness is typically inherited. It is most commonly inherited from mutations on the X chromosome but the mapping of the human genome has shown there are many causative mutations-mutations capable of causing color blindness originate from at least 19 different chromosomes and 56 different genes.
Protanopia, deuteranopia, protanomaly, and deuteranomaly are commonly inherited forms of red-green color blindness which affect a substantial portion of the human population. Those affected have difficulty with discriminating red and green hues due to the absence or mutation of the red or green retinal photoreceptors
