The sRGB standard defines the chromaticities of the red, green, and blue primaries, the colors where one of the three channels is nonzero and the other two are zero.The gamut of chromaticities that can be represented in sRGB is the color triangle defined by these primaries, which are set such that the range of colors inside the triangle is well within the range of colors visible to a human ...
A 1775 color triangle by Tobias Mayer. The sRGB color triangle, shown as a subset of x,y space, a chromaticity space based on CIE 1931 colorimetry. A color triangle is an arrangement of colors within a triangle, based on the additive or subtractive combination of three primary colors at its corners.
For example, the white point of an sRGB display is an x, y chromaticity of (0.3127, 0.3290), where x and y coordinates are used in the xyY space. (u′, v′), the chromaticity in CIELUV, is a fairly perceptually uniform presentation of the chromaticity as (another than in CIE 1931) planar Euclidean shape.
Created to describe a typical 1990s CRT screen, sRGB has a limited gamut and is unable to describe every real color. As Wikipedia templates take a hex triplet as input, all colors must have a value in the sRGB range. Fitting a color into the range is known as gamut mapping. The current practice is to use an scRGB interpretation scaled to 0-255.
It is able to store a wider range of color values than sRGB. The Wide Gamut color space is an expanded version of the Adobe RGB color space , developed in 1998. As a comparison, the Adobe Wide Gamut RGB color space encompasses 77.6% of the visible colors specified by the Lab color space , whilst the standard Adobe RGB color space covers just 50.6%.
Normally sRGB is used. CMYK color model: The coordinates in CMYK space as commonly used during color printing. Colors represented by CMYK coordinates vary greatly between printers depending on the inks used. HSV color space: The HSV space is a transformation from RGB space. As a transformation of RGB values, HSV values share the same limitation.
In typography, a bullet or bullet point, •, is a typographical symbol or glyph used to introduce items in a list.For example: Red; Green; Blue; The bullet symbol may take any of a variety of shapes, such as circular, square, diamond or arrow.
Diagram in CIE rg chromaticity space showing the construction of the triangle specifying the CIE XYZ color space. The triangle C b-C g-C r is just the xy = (0, 0), (0, 1), (1, 0) triangle in CIE xy chromaticity space. The line connecting C b and C r is the alychne.
