I'm redoing our play room. I had a gallon of Cool Aqua by Benjamin Moore that I've put on two of the walls. I really love the colour, but I don't want to put it on all four walls, it is very strong. I am having a VERY difficult time trying to find a complimentary colour to do on the other two walls. Right now all the trim and doors are golden oak, but I'm painting all the trim out in white and the doors in black.
I'm putting grey in my entryway (playroom is right off of it and very visible) so I thought about doing grey, maybe metallic silver on the two walls in the play room, and then having yellow accents. I've also considered green again I'm just not sure.
