Painting

Yesterday, Pants and I painted one of the two small bedrooms in our house. The old color was this bright yellow. Because we're putting the house on the market in a few months, we want to repaint everything in a neutral color. We've been using this one paint color called "bone." It's off-white, kinda greyish. When I rolled the first patch of paint onto the yellow wall, my eyes played a trick on me. Against the old yellow paint, the new grey paint looked purple. One of those color-wheel things: yellow is the oposite of purple. It wasn't until the whole room was painted that we finally realized we'd been using purple paint.
