Color blindness
People with color blindness[1] cannot tell the difference between certain colors. They may not see colors at all.
Most color blindness is inherited, usually as simple Mendelian inheritance. Sometimes, it is the result of damage to the eyes, nerves, or the brain. It can be caused by coming into contact with certain chemicals.
Most color blindness is permanent. Some conditions can lead to temporary color blindness. During certain kinds of migraine, some people are unable to tell the difference between certain colors. There is no treatment cure for permanent color blindness.
Many more males are color blind than females. Between five and eight percent of males, but less than one percent of females, are color blind.[2]
People usually think of color blindness as a disability. However, people who are color blind have one advantage: they are sometimes better at seeing through some types of camouflage.[3]
