You can paint your daughter's room virtually any color. Children's rooms are great for a ton of color. You could paint it either pink or blue, or even purple.
It really depends on the shade of blue and pink. Earth tones are always a good choice. Colors such as beige, or gray. They have small samples you get get mixed to test them on the wall first before you commit to an entire gallon.
Take the colors to the paint store and see what colors go good with the items. A pale yellow, pink or light blue might work. Or all three colors might work. You might want to add some accent colors to the room. Your not clear and how pink or blue the colors are.
Well not much goes with pink, but if you painted the walls white it would definitely work. All you would ahve to do it add pink or blue trimming, or some nice wall paper would do.
