Im re-doing my room, color help!?

im thinking light yellow with a chocolate brown trim on the doors and closet. But not a lot of other colors will look good, and i think maybe those coors will be used alot. cause i have a lot of furniture, with not a lot of colors to choose from. so any colors that will look good please tell me! oh and im thinking some brown cheetah print for my bed and chair? is it too young for me (young teen) or too old????? help!
