Bright colors are nice, but dorm rooms can get very cramped and cluttered, so eye-popping colors, while interesting and entertaining in themselves, might make for an unsettling dorm ambience. I would opt for softer, less visually demanding colors (blues, greens, yellows, with a little soft brown tones thrown in) - remember, it's a bedroom, as well as a study room, and is often the only respite from hectic campus life. It might be a good idea to take your daughter to a quilt shop and show her some possibilities of color combinations, and let her see what she likes best. Just watching how she reacts to the colors would give you a clue. Just my thought.
