A useful method for checking where a certain colour lies on the granulation spectrum involves wetting your paper and adding some colour on top. Gently rock the paper back and forth until the pigment settles, and you’ll have your answer. Some colours achieve a more intensely granulated texture on professional paper. These may granulate on their own, but to take it one step further, or to test granulating effects in otherwise smooth pigments like Winsor Blue (Green Shade), again try the Granulation Medium.
