The 7th grade class started with only the primary colors (R,Y,B) in watercolor paint. Next they mixed them to make the secondary and tertiary colors as you can see from the color wheel above. With these mixed colors they painted bands on watercolor paper and tore them to appear as mountains. When overlapped they look like a colorful landscape. What I want to show is that all you need is primary colors and you can make enough colors to paint a landscape.
