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.

Also, the actual displayed colors are subject to the output format used - PAL or NTSC, composite or component video, etc. - and might be slightly different. For simulated images and specific hardware and alternate methods to produce colors other than RGB (ex: composite), see the List of 8-bit computer hardware palettes , the List of 16-bit ...
This format is a part of the OpenGL ES graphics standard extensions [4] for embedded devices such as mobile phones and has been approved by the Khronos Group for use in the WebGL graphics standard for browser-side World Wide Web graphics. [citation needed] Android version 2.2 (Froyo) includes support for ETC1. [5] [3]
The format has been updated several times, adding support for tiles, mipmaps, new compression methods, and other features. [9] In 2007, OpenEXR was honored with an Academy Award for Technical Achievement. [9] OpenEXR 2.0 was released in April 2013, extending the format with support for deep image buffers and multiple images embedded in a single ...
The Quite OK Image Format (QOI) is a specification for lossless image compression of 24-bit (8 bits per color RGB) or 32-bit (8 bits per color with 8-bit alpha channel RGBA) color raster (bitmapped) images, invented by Dominic Szablewski and first announced on 24 November 2021.
Web colors are colors used in displaying web pages on the World Wide Web; they can be described by way of three methods: a color may be specified as an RGB triplet, in hexadecimal format (a hex triplet) or according to its common English name in some cases. A color tool or other graphics software is often used to
S3 Texture Compression (S3TC) (sometimes also called DXTn, DXTC, or BCn) is a group of related lossy texture compression algorithms originally developed by Iourcha et al. of S3 Graphics, Ltd. [1] [2] for use in their Savage 3D computer graphics accelerator.
