Warped checkerboard coloring page
A checkerboard pushed outward in the middle, so the board seems to swell toward you. Color it as a real checkerboard, every second square dark, and the bulge gets much stronger. Every optical illusion here is strongest at high contrast, so give neighbouring shapes colors far apart in tone: one very light, one very dark.
Fine lines, patterns and many small areas for colored pencils and markers.
