A BIOS Color Attribute is an 8 bit value where the low 4 bits represent the character color and the high 4 bits represent the background color. The name comes from the fact that these colors are used in BIOS interrupts, specifically INT 10h, the video interrupt. When writing text to the screen, a BIOS color attribute is used to designate the ...
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.
An achromatic gray is a gray color in which the red, green, and blue codes are exactly equal. The web colors gray, gainsboro, light gray, dark gray, and dim gray are all achromatic colors. A chromatic gray is a gray color in which the red, green, and blue codes are not exactly equal, but are close to each other, which is what makes it a shade ...
Created to describe a typical 1990s CRT screen, sRGB has a limited gamut and is unable to describe every real color. As Wikipedia templates take a hex triplet as input, all colors must have a value in the sRGB range. Fitting a color into the range is known as gamut mapping. The current practice is to use an scRGB interpretation scaled to 0-255.
Systems with a 6-bit RGB palette use 2 bits for each of the red, green, and blue color components. This results in a (2 2) 3 = 4 3 = 64-color palette as follows: 6-bit RGB systems include the following: Enhanced Graphics Adapter (EGA) for IBM PC/AT (16 colors at once) Sega Master System video game console (32 colors at once)
[2] As of X.Org Release 7.4 rgb.txt is no longer included in the roll up release, [3] and the list is built directly into the server. [4] The optional module xorg/app/rgb contains the stand-alone rgb.txt file. The list first shipped with X10 release 3 (X10R3) on 7 June 1986, having been checked into RCS by Jim Gettys in 1985. [5]
