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.
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.
256 colors, usually from a fully-programmable palette: Most early color Unix workstations, Super VGA, color Macintosh, Atari TT, Amiga AGA chipset, Falcon030, Acorn Archimedes. Both X and Windows provided elaborate systems to try to allow each program to select its own palette, often resulting in incorrect colors in any window other than the ...
graphics mode with 256 colors at once (8-bit) out of 262,144 (18-bit RGB palette); graphics with 65,536 colors at once (16-bit "high color"); text mode with 80×34 characters; 1024 × 768: graphics with 256 colors out of 262,144; text with 85×38 or 146×51 characters; XGA-2 introduced: 640 × 480 graphics with 256 colors out of 16.7M (24-bit ...
A 2-bit indexed color image. The color of each pixel is represented by a number; each number (the index) corresponds to a color in the color table (the palette).. In computing, indexed color is a technique to manage digital images' colors in a limited fashion, in order to save computer memory and file storage, while speeding up display refresh and file transfers.
Because of the low amount of memory and resultant higher speeds of 8-bit color images, 8-bit color was a common ground among computer graphics development until more memory and higher CPU speeds became readily available to consumers. 8-bit color was used in many different applications including: [4] [failed verification]
This article is a list of the color palettes for notable computer graphics, terminals and video game console hardware.. Only a sample and the palette's name are given here. More specific articles are linked from the name of each palette, for the test charts, samples, simulated images, and further technical details (including referenc
The attribute byte associated with every 8×8 pixel cell comprises (from LSB to MSB): three bits for the background color; three bits for the foreground color; one bit for the bright variant for both, and one bit for the flashing effect (alternate foreground and background colors every 0.32 seconds).
