Sometimes when choosing a colour scheme for a kids room, be it a bedroom, playroom or nursery, multicoloured is the only way to go - this room works well with it's multicolours because of it's super crisp white background.
Minifigure storage -get a glass picture frame. put the color of paper you want inside the frame. super glue the bricks to the glass and snap your figures into the bricks! my future kids will play with legos. lots of legos.
