  2. Opponent-process theory - Wikipedia

    en.wikipedia.org/wiki/Opponent-process_theory

    The veracity of this theory, however, has recently been challenged. The main evidence for this theory derived from recordings of retinal and thalamic (LGN) cells, which were excited by one color and suppressed by another. Based on these oppositions, the cells were called "Blue-yellow", "Green-red" and "black-white" opponent cells.

    Thus, the cells are coding complementary colors instead of opponent colors. Pridmore reported also of green–magenta cells in the retina and V1. He thus argued that the red–green and blue–yellow cells should be instead called green–magenta, red–cyan and blue–yellow complementary cells. An example of the complementary process can be ...

  4. Grid illusion - Wikipedia

    en.wikipedia.org/wiki/Grid_illusion

    An example of the scintillating grid illusion. Dark dots seem to appear and disappear at intersections. The scintillating grid illusion is an optical illusion, discovered by E. and B. Lingelbach and M. Schrauf in 1994. [2]

    The Vertical-horizontal illusion is the tendency for observers to overestimate the length of a vertical line relative to a horizontal line of the same length. Vista paradox: Visual tilt effects: Wagon-wheel effect: White's illusion: Wundt illusion: The two red vertical lines are both straight, but they may look as if they are bowed inwards to ...

    The NCS coincides with the CMYK as regards the green-yellow-red segment of the color circle, but differs from it in seeing the saturated subtractive primary colors magenta and cyan as complex sensations of a "redblue" and a "greenblue" respectively and in seeing green, not as a secondary color mix of yellow and cyan, but as a unique hue. The ...

    Feelings of joy and sadness were strongly associated with the brightness, value, saturation, chroma and lightness of the game being played. The greater the color saturation was in the video game, the more strongly felt these emotions were among the players. Less color saturation in the video game predicted higher feelings of fear. [88]

  8. Color vision - Wikipedia

    en.wikipedia.org/wiki/Color_vision

    It states that the visual system interprets color in an antagonistic way: red vs. green, blue vs. yellow, black vs. white. Both theories are generally accepted as valid, describing different stages in visual physiology, visualized in the adjacent diagram. [12]: 168 Green–magenta and blue–yellow are scales with mutually exclusive boundaries.

  9. McCollough effect - Wikipedia

    en.wikipedia.org/wiki/McCollough_effect

    A test image for the McCollough effect. On first looking at this image, the vertical and horizontal lines should look black and white, colorless. After induction, the space between vertical lines should look red and the space between horizontal lines should look green.
