Bedroom Paint Color Advice?

15 years ago, my mother bought a house to be used for a daycare. Since this was its purpose, she has never changed much of the upstairs. Now she is considering/planning to sell and wants to paint a certain bedroom. The problem is, everything is pink. It came that way. It has rose colored carpet, pink walls, even the blinds are pink. She has no ability to color match in any way. I keep telling her, neutral tones and have managed to get her to listen after much arguing, with the downstairs rooms.

The house is in a depressed area and, as the realtor told her, there is "no" housing market here, so she is hanging onto it for a little while and is eager (too) to repaint all the walls in order to increase the chances of a sale, but has little money to put into it and seems to think it is just fine to paint all the walls of every room the same color. What would be a nice, neutral color to paint a bedroom that is not so gender specific and would possibly increase sales? It must match the rose colored carpet.
