Additive color, or "additive mixing", is a property of a color model that predicts the appearance of colors made by coincident component lights, i.e. the perceived color can be predicted by summing the numeric representations of the component colors. Modern formulations of Grassmanns laws describe the additivity in the color perception of light mixtures in terms of algebraic equations. It is important to note that additive color predicts perception and not any sort of change in the photons of light themselves. These predictions are only applicable in the limited scope of color matching exp ...

## All horses are the same color

The horse paradox is a falsidical paradox that arises from flawed demonstrations, which purport to use mathematical induction, of the statement All horses are the same color. There is no actual contradiction, as these arguments have a crucial flaw that makes them incorrect. This example was originally raised by George Polya in a 1954 book in different terms: "Are any n numbers equal?" or "Any n girls have eyes of the same color", as an exercise in mathematical induction. It has also been restated as "All cows have the same color". The "horses" version of the paradox was presented in 1961 i ...

## Analogous colors

Analogous colours are groups of three colours that are next to each other on the colour wheel, and a tertiary. Red, orange, and red-orange are examples. The term analogous refers to having analogy, or corresponding to something in particular. An analogous color scheme creates a rich, monochromatic look. It is best used with either warm or cool colors, creating a look that has a certain temperature as well as proper color harmony. While this is true, the scheme also lacks contrast and is less vibrant than complementary schemes.

## Bastard color

In theatre lighting, a bastard color is a color, typically in a color gel, wherein the predominant color is blended with small amounts of complementary colors; for example, a "bastard orange" gel would produce predominantly orange light with undertones of blue. Bastard colors appear warmer and more natural than pure colors and are used to replicate natural light.

## Benham's top

Benhams top, also called Benhams disk, is named after the English newspaper-man, amateur scientist, and toymaker Charles Benham, who in 1895 sold a top painted with the pattern shown. When the disk is spun, arcs of pale color, called Fechner colors or pattern-induced flicker colors, are visible at different places on the disk. Not everyone sees the same colors. Benham was inspired to propagate the Fechner color effect through his top after his correspondence with Gustav Theodor Fechner, who had observed and demonstrated the said effect. Benhams top made it possible for speakers of the Engl ...

## Bezold effect

The Bezold effect is an optical illusion, named after a German professor of meteorology, Wilhelm von Bezold, who discovered that a color may appear different depending on its relation to adjacent colors. It happens when small areas of color are interspersed. An assimilation effect called the von Bezold spreading effect, similar to spatial color mixing, is achieved. The opposite effect is observed when large areas of color are placed adjacent to each other, resulting in color contrast.
