It used to be that watercolor painters had few options beyond white paper or a few colored boards. Now you can turn almost any surface into a toned or black ground for watercolor painting, as well as collage, pastels, pencils and mixed media work. Buff Titanium is great for value studies and provides a gorgeous, classic-looking surface for work in neutral grays, earthy reds, black and white. Mars Black makes Luminescent Watercolors pop and also provides an exciting, unexpected background for all your standard watercolor paints. Soft pastels, graphite and watercolor pencils show up beautifully on both the buff and black. Titanium White, as well as turning any surface into Watercolor Paper, allows you to rescue areas within a painting done on Watercolor paper! Its so easy to apply Ground over an area within a painting that needs rescuing—or for working on different compositional areas. You can also lift and scrub without damaging the painting surface.
