The color box at right shows the most intense yellow representable in 8-bit RGB color model; yellow is a secondary color in an additive RGB space. This color is also called color wheel yellow . It is at precisely 60 degrees on the HSV color wheel , also known as the RGB color wheel ( Image of RGB color wheel: ).
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.

The name of the model comes from the initials of the three additive primary colors, red, green, and blue.
Yellow is the color between green and orange on the spectrum of light. It is evoked by light with a dominant wavelength of roughly 575–585 nm. It is a primary color in subtractive color systems, used in painting or color printing. In the RGB color model, used to create colors on television and computer screens, yellow is a secondary color ...
This list of monochrome and RGB palettes includes generic repertoires of colors ( color palettes) to produce black-and-white and RGB color pictures by a computer's display hardware. RGB is the most common method to produce colors for displays; so these complete RGB color repertoires have every possible combination of R-G-B triplets within any ...
Brown colors are dark or muted shades of reds, oranges, and yellows on the RGB and CMYK color schemes. In practice, browns are created by mixing two complementary colors from the RYB color scheme (combining all three primary colors). In theory, such combinations should produce black, but produce brown because most commercially available blue ...
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. The web colors list is descended from it but differs for certain color names.
RGBA stands for red green blue alpha. While it is sometimes described as a color space, it is actually a three-channel RGB color model supplemented with a fourth alpha channel. Alpha indicates how opaque each pixel is and allows an image to be combined over others using alpha compositing, with transparent areas and anti-aliasing of the edges of ...
