Just back from Ohio, where I taught a 2-day Beginning Watercolor Workshop. We painted Color-Wheel Mandalas, using photo references, and Pumpkins, drawn and painted from life.
After drawing the circle and separating it into 6 sections (using compasses, protractors, and straight-edges), they painted washes of color, using only the 3 primary colors. An Aureolin Yellow wash was painted on the yellow/green/orange sections. A Quinacridone Rose wash was painted on the red/orange/violet sections. A Cobalt Blue wash was painted on the blue/green/violet sections.
After doing the underpainting on the Color Wheel, we painted a wet-in-wet mingling on a separate piece of paper, using warm colors, and sprinkling salt/spattering color on it.
Using photo references, they drew and painted each of the color sections of the Wheel. Those who had time, painted a pumpkin from life.
Every one of the 9 ladies at the workshop did a beautiful job, and I'm fairly certain that they will be painting again! Yea!
