My room is yellow with white cabinetry. I love yellow - it makes me happy. As for the true color of the fabric, I think the lighting makes more difference than the wall color.
We had a thread about the best color of a design wall, and I recall that white was not it. I think a light grey or beige flannel was preferred.
I think you should pick a color that makes YOU feel good and that you could stand to stay in for long stretches of time.
