  2. List of monochrome and RGB color formats - Wikipedia

    en.wikipedia.org/wiki/List_of_monochrome_and_RGB...

    It must be noticed that not all systems using 16-bit color depth employ the 16-bit, 32-64-32 level RGB palette. Platforms like the Sharp X68000 home computer or the Neo Geo video game console employs the 15-bit RGB palette (5 bits are used for red, green, and blue), but the last bit specifies a less significant intensity or luminance.

  3. RGB color model - Wikipedia

    en.wikipedia.org/wiki/RGB_color_model

    High-end digital image equipment are often able to deal with larger integer ranges for each primary color, such as 0..1023 (10 bits), 0..65535 (16 bits) or even larger, by extending the 24-bits (three 8-bit values) to 32-bit, 48-bit, or 64-bit units (more or less independent from the particular computer's word size).

  4. List of color palettes - Wikipedia

    en.wikipedia.org/wiki/List_of_color_palettes

    Super High Res 4-, 8-, 16- and 256-color graphic modes, from 4096 (4 bits of each of red, green, and blue), with some palette choice restrictions in 80-column modes. MCGA and VGA for IBM PC/AT (1987) Medium 256- and high resolution 16-color graphic modes, from 262,144 (6 bits of each of red, green, and blue).

  5. RGBA color model - Wikipedia

    en.wikipedia.org/wiki/RGBA_color_model

    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.

  6. List of software palettes - Wikipedia

    en.wikipedia.org/wiki/List_of_software_palettes

    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.

  7. Color depth - Wikipedia

    en.wikipedia.org/wiki/Color_depth

    24 bits almost always use 8 bits each of R, G, and B (8 bpc). As of 2018, 24-bit color depth is used by virtually every computer and phone display [citation needed] and the vast majority of image storage formats. Almost all cases of 32 bits per pixel assigns 24 bits to the color, and the remaining 8 are the alpha channel or unused.

  8. Web colors - Wikipedia

    en.wikipedia.org/wiki/Web_colors

    In some uses, hexadecimal color codes are specified with notation using a leading number sign (#). [1] [2] A color is specified according to the intensity of its red, green and blue components, each represented by eight bits. Thus, there are 24 bits used to specify a web color within the sRGB gamut, and 16,777,216 colors that may be so specified.

  9. Indexed color - Wikipedia

    en.wikipedia.org/wiki/Indexed_color

    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.
