Twisted cord rings coloring page
Nine rings of small tilted blocks. Every ring is a true circle, but the tilt makes the set read as one spiral winding inward. Color the blocks dark and the rings light to see it at its strongest. 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.
