 To paint just one of these rocks, I started on top of a pale wash and began to paint the top section with more water in the transparent red oxide and less water in the bottom sections and then use this flat brush with just water on it to create some highlights in the top. Added in some color that was mixed with some of the blues because that's going to turn the transparent red oxide into a little more of a grayish tone. Once it was completely dry, use some dry brush technique and just let the paint scuttle over the texture of the watercolor paper. I did the same thing with each one of these rocks, just going back and forth to add more color to each one. You can see this entire video over on my YouTube channel.
