The 5-Pen packs are a great way to get into the Chameleon Color Tones range. These packs are made up of the 20 Chameleon pen colours, broken down into 4 individual sets; Pastel Tones, Primary Tones, Earth Tones and Cool Tones. Each pack is complete with detailed instructions that have useful hints, tips and techniques. Coloring with shadows and shading is what gives your artwork lifelike depth and dimension. Chameleon Color Cards are designed to take the guesswork out of light placement and make highlights, shadows and shading easier to do. Not only are they fun to color, you also get hands on learning! Think of it like coloring with training wheels. The Shading and coloring guides help you get better at understanding how the light plays on different objects and with practice it will get easier to do it with images you create on your own!
