A hex triplet is a six-digit (or eight-digit), three-byte (or four-byte) hexadecimal number used in HTML, CSS, SVG, and other computing applications to represent colors. The bytes represent the red, green, and blue components of the color. The optional fourth byte refers to alpha channel. One byte represents a number in the range 00 to FF (in ...
Systems with a 12-bit RGB palette use 4 bits for each of the red, green, and blue color components. This results in a (2 4) 3 = 16 3 = 4096-color palette. 12-bit color can be represented with three hexadecimal digits, also known as shorthand hexadecimal form, which is commonly used in web design. The palette is as follows:
Initially, the limited color depth of most video hardware led to a limited color palette of 216 RGB colors, defined by the Netscape Color Cube. The web-safe color palette consists of the 216 (6 3) combinations of red, green, and blue where each color can take one of six values (in hexadecimal): #00, #33, #66, #99, #CC or #FF (based on the 0 to ...
2-, 4-, 8-, 16- and 32-color standard graphic modes, EHB 64-color and HAM 4096-color enhanced modes; 2 to 64 color modes pick from a 4096-color master palette (4 bits for each of red, green, and blue), with 64 color mode constructed from 32 normally chosen colors plus a second set of 32 fixed at half the intensity of the first.
For each unique palette, an image color test chart and sample image (truecolor original follows) rendered with that palette (without dithering) are given. The test chart shows the full 8-bit, 256 levels of the red, green, and blue primary colors and cyan, magenta, and yellow complementary colors, along with a full 8-bit, 256 levels grayscale.
RGB (red, green, blue) describes the chromaticity component of a given color, when excluding luminance. RGB itself is not a color space, it is a color model. There are many different color spaces that employ this color model to describe their chromaticities because the R/G/B chromaticities are one facet for reproducing color in CRT & LED displays.
This color scheme is the most varied color scheme because it uses six colors which are arranged into three complementary color pairs, or it could be seen as two color schemes that are complimentary to each other—such as two triadic color schemes or two near-analogous color schemes—or adding a complementary pair to a rectangular tetradic ...
An RG color model is a dichromatic color model represented by red and green primary colors. These can only reproduce a fraction of the colors possible with a trichromatic color space, such as for human color vision. The name of the model comes from the initials of the two primary colors: red and green. The model may be either additive or ...
