Color Blidness

Color blindness

Color blindness in definition is the inability to perceive differences between some or all colors that other people can distinguish. It is most often from genetics, but may also occur because of eye, nerve, or brain damage, or due to exposure to certain chemicals.In that case I believe color blindness is great infromation to know about people. It can now help you know that color blind people need to see colors like blue,black,and red when looking at things to actaully read it.
