one of my stepsons is paritially colorblind. When he was young and dressing himself for school he would come downstairs in the oddess color choices and I would make him go up stairs and change again and again (I thought he was trying to be funny) When I found out from school what the problem was I felt so bad that I didn't see it before. To find out for myself what colors he could see I got a color chart with about 50 different shades and when through them with him. If it was a shade he couldn't identify it was always brown to him. Then when purchasing his clothes in the future I would always buy colors he could see and made sure everything match with everything, sounds like a small thing but it became important to him when he started dating
He didn't have a problem getting his DL, The colors they use for traffic lights he could see.
