These quality Derwent pencils can be mixed with water to alter the level of brightness and to create interesting colour flows. They can also be used dry and due to their soft texture you will find them easy to blend and layer. Watercolour is not permanent like Inktense, so once the colour is dry you can re-wet it and move it about again. This tin contains the following colours: Deep Cadmium, Orange Chrome, Deep Vermilion, Crimson Lake, Imperial Purple, Spectrum Blue, Prussian Blue, Mineral Green, Grass Green, Golden Brown, Copper Beech and Ivory Black.
