One of the most interesting facts about color blindness is about inheritance of the disorder. Color blindness is one of the genetic disorders in humans. As the most common form of this deficiency is related to X chromosome or color blindness chromosome, color blindness tends to be more common in males than in females. But color blindness genetics also suggest that even though women are not color blind themselves, they are very active carriers of color blindness.
