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.
Since Windows 95, these additional colors can be changed by the system when a color scheme needs custom colors, [3] reducing their utility as static, unchanging palette entries. The complete 20-color Windows system palette is: 0 — black. 246 — cream. 1 — dark red. 247 — medium grey.
Deep reddish purple. B: Normalized to [0–255] (byte) The color Byzantium is a particular dark tone of purple. It originates in modern times, and, despite its name, it should not be confused with Tyrian purple ( hue rendering ), the color historically used by Roman and Byzantine emperors. The latter, often also referred to as "Tyrian red", is ...
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.
The color purple, as defined in the X11 color names in 1987, is brighter and bluer than the HTML/CSS web color purple shown above as purple (HTML/CSS color). This is one of the very few clashes between web and X11 colors . This color can be called X11 purple . Veronica prostrata, for which the color veronica is named.
The 8-bit RGB palettes (also known as 3-3-2 bit RGB) use 3 bits for each of the red and green color components, and 2 bits for the blue component, due to the lesser sensitivity of the common human eye to this primary color. This results in an 8×8×4 = 256-color palette as follows: Red. #000000.
HSL and HSV are the two most common cylindrical-coordinate representations of points in an RGB color model. The two representations rearrange the geometry of RGB in an attempt to be more intuitive and perceptually relevant than the cartesian (cube) representation. Developed in the 1970s for computer graphics applications, HSL and HSV are used ...
A diagram demonstrating additive color with RGB. The RGB color model is an additive color model [1] in which the red, green and blue primary colors of light are added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.
