Portable Network Graphics is a raster-graphics file format that supports lossless data compression. PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF)—unofficially, the initials PNG stood for the recursive acronym "PNG's not GIF".
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; they can be described by way of three methods: a color may be specified as an RGB triplet, in hexadecimal format or according to its common English name 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, red and pink representations of the colors of those cnidarians known as precious corals.
Powder blue is a pale shade of blue. As with most colours, there is no absolute definition of its exact hue. Originally, powder blue, in the 1650s, was powdered smalt used in laundering and dyeing applications, and it then came to be used as a colour name from 1894.
Fuchsia is a vivid pinkish-purplish-red color, named after the color of the flower of the fuchsia plant, which was named by a French botanist, Charles Plumier, after the 16th-century German botanist Leonhart Fuchs.
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.
Forest green is a green color said to resemble the color of the trees and other plants in a forest.
In optics, orange has a wavelength between approximately 585 and 620 nm and a hue of 30° in HSV color space. In the RGB color space it is a secondary color numerically halfway between gamma-compressed red and yellow, as can be seen in the RGB color wheel. The complementary color of orange is azure. Orange pigments are largely in the ochre or cadmium families, and absorb mostly blue light.
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 are shown below.
Pink colors are usually light or desaturated shades of reds, roses, and magentas which are created on computer and television screens using the RGB color model and in printing with the CMYK color model. As such, it is an arbitrary classification of color.
The color magenta has notable tints and shades. These various colors are shown below.
Varieties of the color blue 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 blue or other hue mixed with white, a shade being mixed with black. A large selection of these colors are 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.
Violet is a color term derived from the flower of the same name. There are numerous variations of the color violet, a sampling of which are shown below.
