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.
Web colors are colors used in displaying web pages on the World Wide Web, and the methods for describing and specifying those colors. Colors may be specified as an RGB triplet or in hexadecimal format or according to their common English names in some cases. A color tool or other graphics software is often used to generate color values. In some uses, hexadecimal color codes are specified with notation using a leading number sign (#). A color is specified according to the intensity of its red, green and blue components, each represented by eight bits. Thus, there are 24 bits used to specify a web color within the sRGB gamut, and 16,777,216 colors that may be so specified.
The various tones of the color coral are orange and red representations of the colors of those cnidarians known as precious corals.
Dodger blue is a rich bright tone of the color azure named for its use in the uniform of the Los Angeles Dodgers. It is also a web color used in the design of web pages. The web color is not used in the Dodgers' uniform but rather resembles the lighter blue used throughout Dodger Stadium.
Lemon or lemon-color is a pale yellow color, the color of the lemon fruit.
Maroon is a brownish crimson color that takes its name from the French word marron, or chestnut. "Marron" is also one of the French translations for "brown".
Lime is a color that is a shade of yellow-green, so named because it is a representation of the color of the citrus fruit called limes. It is the color that is in between the web color chartreuse and yellow on the color wheel. Alternate names for this color included yellow-green, lemon-lime, lime green, or bitter lime.
Spring green is a color that was traditionally considered to be on the yellow side of green, but in modern computer systems based on the RGB color model is halfway between cyan and green on the color wheel.
Aqua is a variation of the color cyan. The web color aqua is identical to the web color cyan. It was one of the three secondary colors of the RGB color model used on computer and television displays. In the HSV color wheel aqua is precisely halfway between blue and green. However, aqua is not the same as the primary subtractive color process cyan used in printing.
Varieties of the color green may differ in hue, chroma or lightness, or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a green or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below.
Varieties of the color red may differ in hue, chroma or lightness, or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a red or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below.
Varieties of the color yellow may differ in hue, chroma or lightness, or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a yellow or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below.
Shades of white are colors that differ only slightly from pure white. Variations of white include what are commonly termed off-white colors, which may be considered part of a neutral color scheme.
Variations of gray or grey include achromatic grayscale shades, which lie exactly between white and black, and nearby colors with low colorfulness. A selection of a number of these various colors is shown below.
The color cyan, a greenish-blue, has notable tints and shades. It is one of the subtractive primary colors along with magenta, and yellow.
Shades of brown can be produced by combining red, yellow, and black pigments, or by a combination of orange and black—as can be seen in the color box at right. In the RGB color model used to create all the colors on computer and television screens, brown is made by combining red and green light at different intensities. Brown color names are often not very precise, and some shades, such as beige, can refer to lighter shades of yellow and red rather than darker ones. The commonality is that such colors are less saturated than colors perceived to be orange. Browns are usually described as light or dark, reddish, yellowish, or gray-brown. There are no standardized names for shades of brown; the same shade may have different names on different color lists, and sometimes the one name can refer to several very different colors. The X11 color list of web colors lists seventeen different shades of brown, but the complete list of browns is much longer.
