Mix this pencil with water to create interesting colour flows. Colour is more subtle and you can use it dry, because they have such a soft texture you will find it easy to blend and layer. Watercolour is not permanent, so once the colour is dry you can re-wet it and move it about again.
Wet paper for a more intense color with soft edges, or wet the pencil first for rich, textured lines.
