Yes. Let's say you are working in watercolor and have an ultramarine blue shadow color. If you are painting an orange, the local orange color of the orange will blend perfectly and naturally on top of the blue shadow to create the perfect shadow tone for the orange. It's like magic.
Your ability to lay down such nice smooth tones over large areas is amazing. Do you build up the painting in grays first ala Alex Ross then go over that with the color washes or do you just jump into the color?
