Instead the effect is additive and not dependant on contrast at all - something else that kind of surprised me. So the lighter yours walls and ceilings are generally, the taller your room will look. To explain further or more dramatically, a room with black walls a white ceiling will still appear less tall than a room with white walls and a white ceiling.
Moral of the story? If you want to maximize the perceived height of a space, keep your colours on the light side - all around and up high - and choose whatever type of floor your heart desires.
Happy weekend to all!
