I bought the curtains ages ago, but they didn't really look right with my yellow walls, so I painted the walls white and now the pattern really pops. I also decided to repaint my brown dresser a similar green to the green in the curtains. You'll also notice that the colors in the crazy lampshades mirror the colors in the painting.
Colors used in my room
The color on the walls is Behr Polar Bear White. There are loads of other colors in the furnishings, including green, red, pink and brown.
Tips for using color successfully
Pick colors from a rug, painting, or curtain and repeat them throughout the room. But above all, have fun and don't worry too much about what other people think.
