With Renee's help again, I got the walls all painted. The north and south walls are yellow. The west wall is orange, and the east wall is blue on both the top and bottom "floors ." My original plan was to paint the bottom "floor" green, but Renee picked a very bright shade of green that makes me concerned it will be tiring to look at. Also, the kids' door is already green, so that will be a lot of green on the first floor. I already bought the green paint, but I am hesitant to use it. I chose to play it safe and painted the bottom west wall blue too. But now the play house feels smaller with blue on the top and bottom east walls.
