I think this was a good little tip when deciding upon a compromise regarding the use of bright colors. When I was a teen, I remember painting the inside of my desk hutch brighter colors. It worked well...I didn't get tired of it & it didn't bother the parental unit.
Another compromise would be to let the bedding &/or draperies to be brighter colors. While these options are more obvious, they are also easily changed out!
