I really think that your daughter is the one who should pick a colour . Are you changing the bedding ?

She chose this bedding so it's staying. She likes blue but not sure which way to go. It's not a very big bedroom.

Perhaps a very light aqua to go with the turquoise in the sheets? SW 6498

Hello. In my opinion girls suit pink or gently violet color. But I would paint this room color hues of a sea wave. Also curtains on a window are necessary.

I would paint it SW Repose grey or even a lighter grey. Bring in some bright colors with a rug and some wall art that she likes. I love the bedding!
