Big checker waves coloring page
Rows of large squares, each row lifted a little more than the last, so straight rows look like they ripple. Color every second square dark and the motion gets 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.
A clear subject with a few details and wide spaces to color.
