The Gradient Effect

For the Gradients Optical Illusions, the blocks are the same shade even though they don't seem to be. They have a shading that gradually gets darker. This is called a gradient. The dividing line in this picture forms where the dark half meets the light half. When this border is uncovered, you see 2 very different shades but when it is covered you see the same shade because your brain can't detect a distinct edge and mistakenly assumes that each block is filled with a uniform shade of gray.
