Daniel Smith has a lot of pigments that granulate, separate, and create interesting textures and patterns. I love them all. So got out a few and have started on a painting of the sea-grape trunks and leaves taken when we were in Florida over the winter.
Do you have any granulating colors? I'm using Lunar Earth, Goethite Brown Ochre, and other good ones for this to get lots of texture in those trunks. Waiting while the pigment dries and adding a bit more water creates even more movement and texture.
