After learning so much interesting facts about color, I wanted to learn more about color blind. I first started out by testing for color blind in this website. http://enchroma.com/test/instructions/ And it told me that I have normal color vision. Then I wondered what causes color blind. I found out people with normal color vision can see about 1 million distinct shades of color. For someone with color blindness, they can only see a much reduced amount of color hues: they can see about 5-10% of the color gamut, with the loss mainly oriented along the red-green axis. This is why people who are colorblind need to take another task while getting their license, since green and red are extremely important colors for drivers. Very interestingly, males are more likely to have color blindness than women. Color blindness is an X-linked recessive trait: 35% of females are carriers of the gene mutation, causing it to be expressed in about 8% males.
People who are color blind can only see shades of color and will definitely find difficulty in living. But they don’t have to give up! Two university of Washington researchers have partnered with a biotech firm on a possible cure for colorblindness. This article was released two days ago (!!) and they are planning to move to human trials within one to two years and seek FDA approval for treatment!
