Deviation: Categorical subdivisions are compared against a reference, such as a comparison of actual vs. budget expenses for several departments of a business for a given time period.
The test chart shows the full 256 levels of the red, green, and blue (RGB) primary colors and cyan, magenta, and yellow complementary colors, along with a full 256-level grayscale. Gradients of RGB intermediate colors (orange, lime green, sea green, sky blue, violet, and fuchsia), and a full hue spectrum are also present.
In a single scan line, even column pixels can have one of the first four colors of the line's assigned palette, and odd column pixels one of the last four colors of the eight. The most simple way to use this mode is having a unique 8-color selection for the entire screen with four duplicate colors (the same to both even and odd pixel columns ...
The complement of a hue is the hue that is opposite it (180 degrees) on the color wheel. Using additive colors, mixing a hue and its complement in equal amounts ...
This is a list of software palettes used by computers. Systems that use a 4-bit or 8-bit pixel depth can display up to 16 or 256 colors simultaneously. Many personal computers in the early 1990s displayed at most 256 different colors, freely selected by software (either by the user or by a program) from their wider hardware's RGB color palette.

Here is an example of color channel splitting of a full RGB color image. The column at left shows the isolated color channels in natural colors, while at right there are their grayscale equivalences: Composition of RGB from three grayscale images. The reverse is also possible: to build a full-color image from their separate grayscale channels.
Quantitative schemes are fundamental to Thematic maps, charts, data science, spreadsheets, and other tools which use graphical means to visualize quantitative data. They are common in heat maps, choropleths and other forms of visualization. These color schemes can be categorized into different classes, depending on the nature of the underlying ...
