simple 2 panel interior door. with a modern styled home I think either a 2 panel door or a flush door looks best, though in a pinch there are some great 5 - 6 panel doors that could work as well. but for me it's always best to keep it simple.
I might have to do teal/turquoise instead of pink so I can incorporate my old living room stuff... What do you think @Lauren Davison Davison Hare? (same concept of white and gray but with teal instead of pink)
