Quick ART tips.
Colorless blender pencils are pigment-free and have a wax-based core which allows you to blend and soften your drawing without affecting your color palette. They allow you to develop thick textures, create uniquely vivid blends and soften hard edges.
Create a shading effect by overlapping your colors using the pencil blender over the entire colored section. Drawing in circular or oval patterns burnishing the color into the tooth of the paper.
