Scintillating grid coloring page
A grid of squares with a small dot at every crossing. Color the squares dark and the gaps light, and dots you are not looking at seem to flicker. 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.
Free for personal, home and classroom use. See the license. Printing tips: how to print coloring pages.
