Mixing Gouache Paints

Before I created my color project inspired by Carleton Varney, I had to learn to mix paint colors. In this color chart, I mixed the twelve primary, secondary, and tertiary colors shown in the third row. The top two rows are tints of the original twelve colors and the bottom rows are their shades. I painted 1" by 1 1/4" swatches onto bristol paper and then glued them to a 9" x 12" sheet of bristol paper.
