Tuesday's Tips and Techniques for Watercolor Painting
Mix the two color equally and deeply and you can achieve a rich black, water it down a bit for the perfect neutral grey.
Add more burnt sienna if you want browner rocks.
Add more ultramarine blue if you want a blue grey rock.
Both burnt sienna and ultramarine blue are sedimentary colors. They have heavy pigments that will sink at different rates within the water. You can achieve neat sedimentary or granulating effects for rocks by mixing these two colors together. It creates a cool textured effect.
I love this combo!
