Dark teal walls accented by lime green and white. Jewel-like and perfect. Too Mature? What colors or styles do you like? Hailey used a pink and green toile until she was 14. I put her room on my fb , it's french. champaine , black,and glass.
If the room is large enough you can use a paint colour as dark as this....if not go for a lighter warm grey. White trim as always. Checkout the really dark floor. Absolutely gorgeous if you have the courage.
