Color charts

Here are some of the color charts I've been doing with oil paints over the past week.  Each of the charts was made with red, yellow, and blue along with white and black for mixing.  I think it's fascinating how the many variations can be produced by mixing the colors and by adding varying amounts of white or black.  I also think the color charts are a great exercise for just learning how to manipulate the paint.  (It's also fun to do illustrations with the leftover paint after the color charts are finished!)
