Derwent Watercolour Pencils are great to use and you can mix them with water to create interesting colour flows. The pencils can be used dry and because they have such a 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. Contains 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 pencils.
