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 color to write the text in. For example, to print a white character with a black background, a color attribute of 0F hex would be used.
There are three bits for the RGB components (generating 8 primary colors at full saturation but 75% luminance - similar to the EBU colour bars) and an intensity bit that controls a variation of the base color (a 75% luminance decrease for white, creating gray; a 50% chroma saturation decrease for the RGB primary colors).
Multi-Tonal Gray. A range of light, medium, and dark gray hues make up Elizabeth McGovern's gorgeous gray hairstyle. A slicked back updo really shows off the spectrum of colors.
This indirect scheme restricts the number of available colors in an image CLUT—typically 256-cubed (8 bits in three color channels with values of 0–255)—although each color in the RGB24 CLUT table has only 8 bits representing 256 codes for each of the R, G, and B primaries, making 16,777,216 possible colors. However, the advantage is that ...
SVG Version of X11 color names SVG1.1 named colors with sRGB hex/dec and HSL codes, at UHD (4K) resolution. Extended colors are the result of merging specifications from HTML 4.01, CSS 2.0, SVG 1.0 and CSS3 User Interfaces (CSS3 UI). [6] Several colors are defined by web browsers. A particular browser may not recognize all of these colors, but ...
In computer graphics, pixels encoding the RGBA color space information must be stored in computer memory (or in files on disk). In most cases four equal-sized pieces of adjacent memory are used, one for each channel, and a 0 in a channel indicates black color or transparent alpha, while all-1 bits indicates white or fully opaque alpha.
The complete rgb.txt defines 101 shades from 'Gray0' (black) up to 'Gray100' (white) in addition to 'Gray' and its variants listed above. The shades are apparently defined by the formula GrayN := round(N% × 255) resulting in e.g. 'Gray96' , which happens to be the same as 'White Smoke'. Similarly 'Dim Gray' is the same as 'Gray41' .
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 ...
