"Onions" is a quick demo I painted for class recently. We clustered tulips, or onions, or strawberries, and I encouraged students to average the shadow shape into one color and value, paint that ONE shape accurately and then build into it with slight shifts in temperature and hue. I find it a lot easier to match value when I am building onto a note instead of next to a note.
As an aside, I can usually find an onion or two at home with a lovely green shoot sprouting. I love to paint them and the shoots can get long and graceful while the onion maintains its integrity as a rounded object... makes for lovely harmony.
