With the predominance of 24-bit displays, the use of the full 16.7 million colors of the HTML RGB color code no longer poses problems for most viewers. The sRGB color space (a device-independent color space [23]) for HTML was formally adopted as an Internet standard in HTML 3.2, [24] [25] though it had been in use for some time before that.
The Allegro library supported in the (legacy) version 4, an emulated 12-bit color mode example code ("ex12bit.c"), using 8-bit indexed color in VGA/SVGA. It used two pixels for each emulated pixel, paired horizontally, and a specifically adapted 256-color palette.
English: Color star using the RGB color model Own work based on: Color star-en.svg and An existing RYB image. This model uses names for hues that are uncommon in color theory and do not reflect standard hue naming.
The most common additive color model is the RGB color model, which uses three primary colors: red, green, and blue. This model is the basis of most color displays. Some modern displays are Multi-primary color displays, which have 4-6 primaries (RGB, plus cyan, yellow and/or magenta) in order to increase the size of the color gamut. For all ...
Additive color or additive mixing is a property of a color model that predicts the appearance of colors made by coincident component lights, i.e. the perceived color can be predicted by summing the numeric representations of the component colors. [1]
In computing, on the X Window System, X11 color names are represented in a simple text file, which maps certain strings to RGB color values. It was traditionally shipped with every X11 installation, hence the name, and is usually located in <X11root> /lib/X11/rgb.txt .
YPbPr or ′ ′ ′, also written as YP B P R, is a color space used in video electronics, in particular in reference to component video cables. Like YC B C R , it is based on gamma corrected RGB primaries; the two are numerically equivalent but YP B P R is designed for use in analog systems while YC B C R is intended for digital video .

For example, sRGB and Adobe RGB are both color spaces based on the RGB color model. However, the green primary of Adobe RGB is more saturated than the equivalent in sRGB, and therefore yields a larger gamut. [63] Otherwise, choice of color space is largely arbitrary and depends on the utility to a specific application. [1]
