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.
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.
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 first row is reserved for a page header and attributes are set with control codes which each occupy one character position giving a maximum resolution of 78×72. Apple II (1977) "Low" (text block) 16-color, "high resolution" (140x192 bitmap) 6-color and "double high" 16-color (NTSC artifact based; actually 280×192 monochrome) graphic modes.
This so-called gamut mismatch occurs for example, when we translate from the RGB color space with a wider gamut into the CMYK color space with a narrower gamut range. In this example, the dark highly saturated purplish-blue color of a typical computer monitor's "blue" primary is impossible to print on paper with a typical CMYK printer. The ...
The initial version of XGA expanded upon IBM's older VGA by adding support for four new screen modes, including one new resolution: [120] [121] 640 × 480 pixels in direct 16 bits-per-pixel (65,536 color) RGB hi-color and 8 bit/px (256 color) palette-indexed mode.
As with sRGB, the RGB component values in Adobe RGB (1998) are not proportional to the luminances. Rather, a gamma of approximately 2.2 is assumed, without the linear segment near zero that is present in sRGB. The precise gamma value is 563/256, or 2.19921875. In coverage of the CIE 1931 color space the Adobe RGB (1998) color space covers 52.1% ...
