Watercolor brush variants paint onto a watercolor layer, which enables the colors to flow, mix, and absorb into the paper. The watercolor layer is created automatically when you first apply a brushstroke with a Watercolor brush variant. The layer lets you control the wetness and evaporation rate of the paper to effectively simulate conventional watercolor media. Most Watercolor brush variants interact with the canvas texture. You can use Watercolor brush variants to apply a watercolor effect to a photo by lifting the canvas to the watercolor layer. For more information, see Water controls and Watercolor.
For more information about additional watercolor brush variants, see Real Watercolor.
To paint directly on the canvas, use a Digital Watercolor brush variant.
