"Pigment channeling" is the term I've coined for a technique I love using to create dynamic interactions using granulating pigments. When you have a lot of pigment on the paper, you can create beautiful effects by adding clear water and tilting the page to let the pigment move and mingle with other hues. Use a light touch, letting things flow instead of pushing and pulling them too much with the brush, and enjoy the effects as the pigment dries and creates amazing colour combinations.
