The widely accepted interpretation of, e.g. the Poggendorff and Hering illusions as manifestation of expansion of acute angles at line intersections, is an example of successful implementation of a "bottom-up," physiological explanation of a geometrical–optical illusion. Ponzo illusion in a purely schematic form and, below, with perspective clues
The aluminium and chrome give the paint a vibrant metallic sparkle, while the glass-like coating acts like a refracting prism, changing the apparent color of the surface as the observer moves. [ 3 ] ChromaFlair paints contain no conventional absorbing pigments ; rather, the pigment is a light interference pigment .
The Fechner color effect is an illusion of color seen when looking at certain rapidly changing or moving black-and-white patterns. They are also called pattern induced flicker colors (PIFCs). A sample of a Benham's top (animated version) The effect is most commonly demonstrated with a device known as Benham's top (also called Benham's disk ...
Demonstration of the Bezold effect. The red seems lighter combined with the white, and darker combined with the black. The Bezold effect is an optical illusion, named after a German professor of meteorology Wilhelm von Bezold (1837–1907), who discovered that a color may appear different depending on its relation to adjacent colors.
Flash lag illusion: Forced perspective: Application used in film and architecture to create the illusion of larger, more distant objects. Fraser spiral illusion: The Fraser spiral illusion, or false spiral, or the twisted cord illusion, was first described by the British psychologist Sir James Fraser in 1908. The overlapping black arc segments ...
Water-color illusions consist of object-hole effects and coloration. Object-hole effects occur when boundaries are prominent where there is a figure and background with a hole that is 3D volumetric in appearance. Coloration consists of an assimilation of color radiating from a thin-colored edge lining a darker chromatic contour. The water-color ...
Pepper's 1890 book includes such detailed explanation of his stagecraft secrets, disclosed in his 1863 joint application with co-inventor Henry Dircks to patent this ghost illusion technique. [ 15 ] The hidden area is typically below the visible stage but in other Pepper's Ghost set-ups it can be above or, quite commonly, adjacent to the area ...
Although op art is a unique style, it has similarities with styles such as abstract expressionism (color field painting). Although color field painting does not give us illusions, similarities can still be found. We can see that both of these styles are minimalist, only a few colors prevail, and no object or plot is shown.
