Each of my rooms (and some walls in the same room) are all different colors
Den/Kitchen/Dining room - bright yellow and bright green
Master BR - periwinkle
Master BA - pink!
Guest room and guest bath - robin's egg blue
Basement - grey
Basement bathroom - bright green
Laundry room - white
It's a bright house with lots of wood walls, wood ceilings and windows so I THINK I can get away with it - though my painter told me I'd have to repaint the MBR/MBA to sell the house to anyone with a male in the family ;)
