Cafe wall illusion coloring page
Bands of bricks shifted sideways against each other. The long lines between the bands are perfectly straight, but once the bricks are colored dark and light they look like they slope. Every optical illusion here is strongest at high contrast, so give neighbouring shapes colors far apart in tone: one very light, one very dark.
