Paint the Onion
A classic exercise in botanical watercolor instruction is painting an onion, because color and shape in onions is relatively simple, and onions are naturally translucent, like watercolors. This image shows five steps for painting, beginning with lightest colors, building them up slowly in layers, and ending with dark line work and white highlights. Colors used are yellow ochre, burnt sienna, raw sienna, burnt umber, sap green, lemmon yellow, and white gouache.
