An optical effect caused by the tendency of contrasting forms and colors to emphasize their difference when they are placed together.
An idea that our perception of a color or apparent value is influenced by the background against which the color or value is seen. e.g. a gray glove placed on a black ground looks bright, but the same glove placed on white, snowy ground appears much darker.
When two different color tones come into direct contact, the contrast intensifies the difference between them.
The tendency of complementary colors to seem brighter and more intense when placed side by side.
The phenomenon in which the perceived color of an area of a scene tends to take on a hue opposite to that of the surrounding area. Thus a grey square on a red background will take on a greenish tint.
a visual effect where colors adjacent to each other appear to influence each other, appearing to shift their hues towards the opposing complement. An example is a red square within a larger square of neutral gray, where the gray will appear to be greenish
An illusion in vision in which equal light intensities appear different as a result of differing surrounding intensities.
The ability of the eye to process hues depending on the surrounding colors. The phenomenon of simultaneous contrast results from the fact that the human eye does not reproduce colors as accurately as possible in accordance with their physical values, but tries to emphasize differences. This also means that the change of a color tone in a color design may fundamentally change the character of the design.
Simultaneous contrast refers to the manner in which the colors and/or brightnesses of two different objects affect each other. The effect is more noticeable when shared between objects of complementary color.
