    I once knew a girl who was colorblind. Both her parents were too. It’s rare but it can happen.

        I didn’t know her well enough to ask. She was a friend of a friend, and this was over a decade and a half ago.

        the gene for red green color blindness is carried on the X chromosome so a woman can have it it is just very rare. Now blue yellow color blindness is much much rarer and carried on a different chromosome so men and women have it equally
