it depends on what colors he see because i'm also colored blind i get my blue and greens mixed up and it also hard to tell the differance between bright colors also. i have to ask my husband if the clothes i pick out for the the girls for school match cuz there are times where i will grab a blue shirt and green pants and i will think they match but my husband tells me no. my point is make them colors that he can see and knows so that way he can find them and he will have fun. you could alse make them bright colors so he can see them.
