I wanted a quick and simple art project that introduced something new and practiced something old. We reviewed our tape resist technique using tape to make a skewed 3x3 grid. Then I showed the kids how to start with a primary color and mix in white to make a lighter version and black to make a darker version. We made light and dark red, blue, and yellow and filled in our grid with all nine colors. Then we talked about which ones we liked the best and what feelings might be associated with different sorts of colors. Fun was had by all and the entire project only took about 20-30 minutes.
