Watercolor Illusion

What: The Watercolor Illusion is one of those gorgeous ones where your brain is just… painting things that aren’t there. The thing about this thats beautiful, is that it’s easily paintable (water colors obviously) with your own watercolors, on physical paper. You should effectively be able to look at this illusion and figure it out (it seems to work for me in greys/blacks/whites so its color blind-independent?) … the lines drawing the shapes have a subtle shading to them in one direction, not too dissimilar to water color painting.
