Coloring with shadows and shading is what gives 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. The cards feature designs printed on high-quality 120 lb. card stock. Each design comes with a full-color guide showing light source, highlights, shadows and shading. The shading and color guides are reversible; each image shown in grey scale on the other side so artists can use their own color selections. The 4 x 6 format is ideal for framing, use as a post card, mounting on a greeting card or adding to mixed media journals. Available in packages of 16 cards including two cards each of eight different designs.
