Note: Colors swatches are shown in mass tone, at top, mixed with an equal amount of water and brushed out toward the bottom. All pictures of color swatches in this web site are only approximations of the actual color of the watercolor paint. We have taken every care to match the color in these pictures on calibrated color monitors to the actual color. However, because of the wide variance in color monitors the results you get may vary.
