Are the two squares the same color?

Are the two squares the same color?

Why do the two stacked squares appear to be different but the color is the same?

The two blocks are, in fact, the exact same colour and only appear different due to the effect of the darker and lighter shading across the middle.

How does checkerboard illusion work?

These illusions work because of the way the brain understands contrast and shadows. That light source casts a shadow on the checkerboard, supposedly making all of the squares that lie in the shadow’s path darker, but not so dark that the lighter and darker squares inside and outside of the shadow are indistinguishable.

What is the Adelson’s checker shadow illusion?

In Adelson’s checkerboard shadow illusion, squares of equal luminance appear lighter or darker depending on whether they are inside or outside a cast shadow1. In some color variations, illusion magnitude is attenuated by specific colors of the cast shadow.

Is there such a thing as the same color illusion?

Are there two squares that are the same color?

By joining the squares marked A and B with two vertical stripes of the same shade of gray, it becomes apparent that both squares are the same.

Is the checker shadow illusion a two dimensional illusion?

However, within the context of the two-dimensional image, they are of identical brightness, i.e., they would be printed with identical mixtures of ink, or displayed on a screen with pixels of identical colour. A rectangle of the same color has been drawn connecting the two areas of the image.
