What would be a good color ?

Hi so I’m huge on books, and I found this super cute doll house book shelf for my daughters room. Of course my fiancé says we don’t have to paint it , because that’ll be one less thing for him to do . Lol

I don’t like the mint color , but I’m not sure what other colors would look nice ? I like yellow and bright colors, I was thinking maybe to paint each little room different colors or should I keep it all the same ? And helpful tips or even pictures of colors schemes would be nice !
