Small room awful blue carpet.

Maybe you can compromise with your daugher on what color she likes. Think about this: what if something happens where you must sell the house? Keep the color neutral. In the mean time, find some accessories that will complement the carpet. Your daughter is the one that will have to sleep in the room, so talk to her and make sure that this is a color she is willing to keep.

Hello Maddie-

Orange is the color opposite blue on the color wheel, therefore it is considered the most complementary color for blue.  Try a pale peachy version on the walls, and use lots more wherever possible (furniture & curtains, for example) to neutralize the dark blue.  If you want to really splash color around, yellow and purple also go well with both blue and orange.  If you go with peach on the walls, stay pastel with your accents, too.  Have fun!                LB12star
