Speaking of home decorating (What, you didn't just here me speaking of decorating?), it's hard enough to mix and match basic colors without tackling the subtle nuances of paint colors.
So here is a fun exercise to see how well you know the names of different colors (offered by one paint company anyway). Just keep in mind that if you have your screen set to black and white, you aren't going to do very well.
Also, if anyone knows of the equivalent test for wallpaper, linoleum, or brickwork, please send it! I'm always looking for tests to fail.
