Painting this room an eggplant purple would be really pretty, and would be neutral for a teenage girl. It wouldn't be too feminine or too masculine! It would look good with the bed frame you currently have and you would easily be able to find curtains that match

Also consider a soft sky blue for the wall behind the bed. The other three walls can be a tonal white and the blue can then be picked up again in the accessories like bedding and an area rug. The single wall color works well for teenagers because they tend to change their mind often and, if need be, you can easily change the back wall color accordingly.

what style room do you want? blue or pink are popular choices

Or both;)

Thanks for all your advise!!!!!!!! This what we decided to do.
