Cet article est une liste des palettes de couleurs pour remarquable infographie , terminaux et console de jeu vidéo matériel.

Seul un échantillon et le nom de la palette sont donnés ici. articles plus spécifiques sont liés à partir du nom de chaque palette, pour les cartes de test, des échantillons, des images simulées, et d'autres détails techniques (y compris les références).

Dans le passé, les fabricants ont mis au point de nombreux systèmes d'affichage différents dans une base concurrentielle, non-collaboration (à quelques exceptions près, comme le VESA consortium), la création de nombreux propriétaires, les instances de l' affichage non standard différents matériels . Souvent, comme avec les premiers personnels et les ordinateurs à domicile , une machine donnée employé son sous - système d'affichage unique, avec sa palette de couleurs aussi unique. En outre, les logiciels développeurs avaient utilisé les capacités de couleur des systèmes d'affichage distincts de plusieurs façons différentes. Le résultat est qu'il n'y a pas de nomenclature ou classement taxonomie norme commune unique qui peut englober tous les palette de couleurs de l'ordinateur.

Afin d'organiser le matériel, les palettes de couleurs ont été regroupés selon des critères arbitraires mais rationnels. Tout d' abord, monochrome générique et complète RVB répertoires communs à différents systèmes d'affichage de l' ordinateur. Deuxièmement, les répertoires de couleurs habituelles utilisées pour les systèmes d'affichage qui emploient des couleurs indexées techniques. Et enfin, la couleur des palettes fabricants spécifiques mises en œuvre dans de nombreux premiers représentatifs des ordinateurs personnels et des consoles de jeux vidéo de différentes marques.

La liste des palettes d'ordinateurs personnels est divisé en deux catégories: 8-bit et 16-bit machines. Ce ne vise pas à une véritable catégorisation stricte de ces machines, car les architectures mixtes existent également (16 bits des processeurs avec un 8-bit bus de données ou les processeurs 32 bits avec un bus de données 16 bits, entre autres). La distinction est plus basée sur les grandes 8 bits et 16 bits âges informatiques ou générations (environ 1975-1985 et 1985-1995 respectivement) et leur associé état de l'art en couleurs des capacités d'affichage.

Voici le tableau d'essai de couleur commune et de l'image échantillon utilisé pour rendre chaque palette dans cette série d'articles:

List of monochrome and RGB palettes

Article détaillé : List of monochrome and RGB palettes.

Aux fins du présent article, la palette monochrome terme désigne un ensemble d'intensités pour un affichage monochrome, et la palette RVB terme est défini comme l'ensemble des combinaisons de données RVB affichage peut offrir en mélangeant toutes les intensités possibles du rouge, primaires vertes et bleues disponibles dans son matériel.

Ce sont des répertoires complets génériques de couleurs pour produire en noir et blanc et RGB images couleur par le matériel d'affichage, pas nécessairement le nombre total de ces couleurs qui peuvent être affichées simultanément dans un texte donné ou en mode graphique de toute machine. RGB est la méthode la plus courante pour produire des couleurs pour les écrans; de sorte que ces répertoires complets de couleur RVB ont toutes les combinaisons possibles de triplets RVB sein un nombre maximum donné de niveaux par composant.

Pour le matériel spécifique et des méthodes différentes pour produire des couleurs de RVB , consultez la Liste des palettes de matériel informatique et de la Liste des consoles de jeux vidéo sections.

Pour divers arrangements et sortes de couleurs, y compris les logiciels d' autres arrangements RGB complets possibles dans 8 bits de profondeur affiche, consultez la Liste des palettes de logiciels section.

Palettes à niveaux de gris

	4-bit Grayscale 2⁴ = 16 levels of gray		16 levels of gray, with Floyd-Steinberg dithering
	8-bit Grayscale 2⁸ = 256 levels of gray

Regular RGB palettes

These full RGB palettes employ the same number of bits to store the relative intensity for the red, green and blue components of every image's pixel color. Thus, they have the same number of levels per channel and the total number of possible colors is always the cube of a power of two. It should be understood that 'when developed' many of these formats were directly related to the size of some host computers 'natural word length' in bytes—the amount of memory in bits held by a single memory address such that the CPU can grab or put it in one operation.

	3-bit RGB 2³ = 8 colors Modèle:BullMore than the four colors available with the CGA video standard used ca. 1981-84.		3-bit RGB, with Floyd-Steinberg dithering
	6-bit RGB 4³ = 64 colors		9-bit RGB 8³ = 512 colors
	12-bit RGB 16³ = 4096 colors		15-bit RGB 32³ = 32,768 colors (HighColor)
	18-bit RGB 64³ = 262,144 colors		24-bit RGB 256³ = 16,777,216 colors (TrueColor) Modèle:BullOften referred to as 'RGB24'. Further: Adding another 8-bit grayscale channel 'AlphMask or 'Alpha channel'* creates 'RGB32' and gives shading capabilities as are commonly used in .tga and .png file formats.*

Non-regular RGB palettes

These are also RGB palettes, in the sense defined above (except for the 4-bit RGBI, which has an intensity bit that affects all channels at once), but either they do not have the same number of levels for each primary channel, or the numbers are not powers of two, so are not represented as separate bit fields. All of these have been used in popular personal computers.

	4-bit RGBI 2³×2 = 16 colors		3-level RGB 3³ = 27 colors
	3-3-2 bit RGB 8×8×4 = 256 colors		16-bit RGB 32×64×32 = 65,536 colors (HighColor)

List of software palettes

Article détaillé : List of software palettes.

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 later 1980s and 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 color palette.

Usual selections of colors in limited subsets (generally 16 or 256) of the full palette includes some RGB level arrangements commonly used with the 8 bpp palettes as master palettes or universal palettes (i.e., palettes for multipurpose uses).

These are some representative software palettes, but any selection can be made in such types of systems.

System specifics

These are selections of colors officially employed as system palettes in some popular operating systems for personal computers that feature 8-bit displays.

	Microsoft Windows default 16-color palette 16 colors		Microsoft Windows default 20-color palette 20 colors
	Apple Macintosh default 16-color palette 16 colors		RISC OS default 16-color palette 16 colors

RGB arrangements

These are selections of colors based on evenly ordered RGB levels, mainly used as master palettes to display any kind of image within the limitations of the 8-bit pixel depth.

	6 level RGB 6³ = 216 colors		6-7-6 levels RGB 6×7×6 = 252 colors
	6-8-5 levels RGB 6×8×5 = 240 colors		8-8-4 levels RGB 8×8×4 = 256 colors

Other common uses of software palettes

	Grayscale palettes up to 256 levels of gray		Color gradient palettes up to 256 levels of any arbitrary hue
	Adaptive palettes up to 256 picked colors		False color palettes up to 256 continuous-tone colors

List of computer hardware palettes

Articles détaillés : List of 8-bit computer hardware palettes et List of 16-bit computer hardware palettes.

In early personal computers and terminals that offered color displays, some color palettes were chosen algorithmically to provide the most diverse set of colors for a given palette size, and others were chosen to assure the availability of certain colors. In many early home computers, especially when the palette choices were determined at the hardware level by resistor combinations, the palette was determined by the manufacturer.

Many of early models output composite video YPbPr colors. When seen on TV devices, the perception of the colors may not correspond with the value levels for the YPbPr values employed (most noticeable with NTSC TV color system).

For current RGB display systems for PC's (Super VGA, etc.), see the 16-bit RGB and 24-bit RGB for HighColor (thousands) and TrueColor (millions of colors) modes.

For video game consoles, see the List of videogame consoles section.

For every model, their main different graphical color modes are listed based exclusively in the way they handle colors on screen, not all their different screen modes.

The list is ordered roughly historically by video hardware, not grouped by branch. They are listed according to the original model of every system, which implies that enhanced versions, clones and compatibles also support the original palette.
