A color contrast illusion elicited by cross-hatching.
Metallic appearance when viewed anaglyphically.
Adjacent strips of constant lightness create the impression of a scalloped intensity gradient.
Contours affect the appearance of a linear gradient.
Bordering gradients give the appearance of two squares of distinct color.
Fluted square waves give the appearance of stripes.
DOG Lateral Inhibition
A simulation of lateral inhibition processing, using the DOG, or Difference of Gaussians, model.
Another example of simultaneous contrast.
Border coloration causes the illusion of a semitransparent figure above the background.
Illusory dark spots in the junctions of white roads.
Bright and dark stripes appear at the boundary of a linear gradient.
Custom Mach Bands
Shadows surround a moving black object on a white background.
Edges appear on a 2D gradient.
2D Hexagonal Bands
2D Reversed Colors
2D Square Grid
Red Rectangle Image
Flashing dots which run away when you look for them.
A remarkable color brightness effect.
Brightness tends to change depending on its surroundings.
Colors may change appearance based on the colors surrounding.
