I'm guessing you can just head to your local hardware store and grab 4-5 of those paint samples in a multitude of colors. After spraying the outside white (or keeping the original stain), just sand, prime and paint the drawers their desired colors. SUPER simple and easy to update from redecorating project to redecorating project.
I'm thinking you can also do them with slatted furniture pieces like benches, chests or outdoor furniture. Have no idea what I'm talking about? Here's some photos that gave me butterflies.
