I went through this phase where I thought pink and purple matched. To dance class, I'd wear purple tights and pink leg warmers and paint my shoes purple. It was really odd.
I made a circle with a smile for a mouth on yellow paper, because it was sunshiny and bright.
You don't need a uniform color: We used a mixture of brick red, browns and grays, and then threw in seashells, branches and various types of rock, so our walls ended up looking like cave paintings!
