The YIQ color space at Y=0.5. Note that the I and Q chroma coordinates are scaled up to 1.0. See the formulae below in the article to get the right bounds. An image along with its Y, I, and Q components. YIQ is the color space used by the analog NTSC color TV system.
If the system does not have a palette stored for a game, it defaults to the "Dark green" palette (see below). The player can also choose one of 12 false color palettes. Type 1 games can have from 4 to 10 colors, four are for the background plane palette and there are two more hardware sprite plane palettes, with three colors plus transparent each.
The VIC-20 lacks any true graphic mode, but a 22×11 text mode with 200 definable characters of 8×16 bits each arranged as a matrix of 20×10 characters is usually used instead, giving a 3:2(NTSC)/5:3(PAL) pixel aspect ratio, 160×160 pixels, 8-color "high-res mode" or a 3:1(NTSC)/10:3(PAL) pixel aspect ratio, 80×160 pixels, 10-color ...
[10] [11] [12] It uses a non-gamma transfer function (PQ or HLG) and system colorimetry (chromaticity of color primaries and white point) identical to Rec. 2020 system colorimetry. [ 9 ] Others with RGB primaries
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.
When one of the components has the strongest intensity, the color is a hue near this primary color (red-ish, green-ish, or blue-ish), and when two components have the same strongest intensity, then the color is a hue of a secondary color (a shade of cyan, magenta, or yellow). A secondary color is formed by the sum of two primary colors of equal ...

A "color model" is an abstract mathematical model describing the way colors can be represented as tuples of numbers (e.g. triples in RGB or quadruples in CMYK); however, a color model with no associated mapping function to an absolute color space is a more or less arbitrary color system with no connection to any globally understood system of ...
