Web-safe color. v. t. e. 8-bit color graphics are a method of storing image information in a computer's memory or in an image file, so that each pixel is represented by 8 bits (1 byte). The maximum number of colors that can be displayed at any one time is 256 per pixel or 2 8. [1]
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.
Hexadecimal 8-bit RGB representations of the main 125 colors. A color in the RGB color model is described by indicating how much of each of the red, green, and blue is included. The color is expressed as an RGB triplet (r,g,b), each component of which can vary from zero to a defined maximum value. If all the components are at zero the result is ...
e. 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 generate color values.
Web-safe color. v. t. e. Number of bits used to represent a color. Color depthor colour depth(see spelling differences), also known as bit depth, is either the number of bitsused to indicatethe color of a single pixel, or the number of bits used for each color component of a single pixel. When referring to a pixel, the concept can be defined as ...
The most common incarnation in general use as of 2021 is the 24-bit implementation, with 8 bits, or 256 discrete levels of color per channel. [7] Any color space based on such a 24-bit RGB model is thus limited to a range of 256×256×256 ≈ 16.7 million colors.
This layout became popular when 24-bit color (and 32-bit RGBA) was introduced on personal computers. At the time it was much faster and easier for programs to manipulate one 32-bit unit than four 8-bit units. On little-endian systems, this is equivalent to BGRA byte order. On big-endian systems, this is equivalent to ARGB byte order.
TRS-80 Color Computer. The TRS-80 Color Computer is capable of displaying text and graphics contained within a roughly square display matrix 256 pixels wide by 192 lines high. The hardware palette has 9 colors: black, green, yellow, blue, red, buff (almost-but-not-quite white), cyan, magenta, and orange.
