Fixed 16-color palette (1 bit each of red, green, blue, and brightness, with bright white replaced by orange), with 2 colors per block on an 8×1 pixel attribute grid. Commodore Plus/4 (1984) Multicolor and High resolution 16-color graphic modes, from 121-color master palette (black and 15 hues by 8 luminosity levels). Amstrad CPC (1984)
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.
Huge palettes are given directly in one-color-per-pixel color patches. For each unique palette, an image color test chart and sample image (truecolor original follows) rendered with that palette (without dithering) are given. The test chart shows the full 256 levels of the red, green, and blue (RGB) primary colors and cyan, magenta, and yellow ...
The Atari ST series has a digital-to-analog converter of 3-bits, eight levels per RGB channel, featuring a 9-bit RGB palette (512 colors).Depending on the (proprietary) monitor type attached, it displays one of the 320×200, 16-colors and 640×200, 4-colors modes with the color monitor, or the high resolution 640×400 black and white mode with the monochrome monitor.
24-bit palette sample image 24 bit Palette Color Test Chart. This is a full list of color palettes for notable video game console hardware.. For each unique palette, an image color test chart and sample image (original True color version follows) rendered with that palette (without dithering unless otherwise noted) are given.
An adaptive color palette expanding from 2 colors to 256 colors, demonstrating how the image changes (click to see animation) In an application showing many different image thumbnails in a mosaic on screen, the program may not be able to load all the adaptive palettes of every displayed image thumbnail at the same time in the hardware color registers.
Almost all of the least expensive LCDs (such as typical twisted nematic types) provide 18-bit color (64×64×64 = 262,144 combinations) to achieve faster color transition times, and use either dithering or frame rate control to approximate 24-bit-per-pixel true color, [14] or throw away 6 bits of color information entirely.
This shorthand form reduces the palette to 4,096 colors, equivalent of 12-bit color as opposed to 24-bit color using the whole six-digit form (16,777,216 colors). This limitation is sufficient for many text-based documents.
