Stick to high-contrast color pairs (black/white, dark blue/yellow). Make sure adjacent areas remain visually distinct. Soft, similar tones can flatten the 3D illusion. Markers with solid coverage work better than pencils for crisp Op Art effects.

Bridget Riley (UK) and Victor Vasarely (Hungary/France) are considered the founders of Op Art in the 1960s. M.C. Escher, while predating the movement, is also closely associated with mathematical and optical illusion art.

Op Art pages are generally better suited for intermediate and advanced colorists because the optical effect depends heavily on precise, consistent color choices. Beginners may find simpler geometric patterns more approachable before tackling full optical illusion designs.
