Op Art & Optical Illusions Coloring Pages
24 free PDFsOp art uses nothing but lines and shapes to trick the eye. On these pages a checkerboard bulges into a sphere, a checkered tunnel pulls the eye toward its center, wavy stripes seem to ripple, rings of teardrops appear to turn, and a hand looks raised off the page because of the curved lines inside it. The impossible triangle, trident, ring and never-ending staircase are shapes that could not exist in real life.
Classic puzzles are here too, from the vase that is also two faces to the cafe wall whose straight rows look tilted and the duck that is also a rabbit, plus op art hearts, butterflies, cats, fish, a flower, a zebra, an ocean scene and a mandala.

Things to make with your op art & optical illusions coloring pages
Use two colors only
Op art works best with strong contrast. Pick two colors, such as black and white or navy and yellow, and fill neighboring bands or cells in turn so the illusion appears.
Watch the illusion change
Color half of the bulging checkerboard in two colors and leave the other half white, then step back and compare which half looks more three-dimensional.
Solve the classic puzzles
Show the vase-or-faces and the duck-or-rabbit pages to someone else and ask what they see first, then color each version in a different color to show both answers.
Each picture is an individual vector PDF. Print on US Letter, or choose “Fit to page” for A4. Try one copy first to check the margins.

Questions about op art & optical illusions coloring pages
Which op art pages show impossible objects?
The impossible triangle, the impossible trident with round prongs that turn into square bars, the impossible ring and the staircase that climbs around a tower forever are all shapes that look solid on paper but could not be built in real life.
See: Impossible Triangle Illusion · Impossible Trident Illusion · Impossible Ring Illusion · Impossible Staircase Illusion
How should I color an optical illusion?
Most op art works best with two strong colors used in turn: fill one band or cell, skip the next, and repeat. On the bulging checkerboard, the wavy stripes and the checkered tunnel, alternating light and dark is what makes the page seem to move or bulge.
See: Bulging Checkerboard Sphere Op Art · Wavy Stripes Optical Illusion · Checkered Square Tunnel Illusion
Are there op art pages with animals?
Yes. A cat, a fish, a butterfly and a zebra are each filled with curved op art stripes and rings, so the animals seem to bulge or melt into the striped background around them.
