DCI-P3 covers 53.6% [4] of the CIE 1931 chromaticity diagram (see inset image), which describes the color gamut of human color vision. A smaller, practical gamut for comparison is the Pointer's gamut , which consists of diffusely reflecting surface colors.
English: This is a CIE 1931 chromaticity diagram, overlaid with outlines of the color gamuts of sRGB, DCI-P3, Rec2020, AdobeRGB, and ProPhoto. Actual colors are only shown for the SRGB gamut; the remainder of the chromaticity diagram has colors dimmed to indicate they are not representable on a standard monitor.
The type of color profile that is typically used is called an ICC profile. A cross-platform view of color management is the use of an ICC-compatible color management system. The International Color Consortium (ICC) is an industry consortium that has defined: an open standard for a Color Matching Module (CMM) at the OS level; color profiles for:
RGB (red, green, blue) describes the chromaticity component of a given color, when excluding luminance. RGB itself is not a color space, it is a color model. There are many different color spaces that employ this color model to describe their chromaticities because the R/G/B chromaticities are one facet for reproducing color in CRT & LED displays.
English: RGB primaries of common color spaces (BT.2020, sRGB, BT.709, DCI-P3, SMPTE-C, NTSC and PAL). Image is encoded with a ICC profile and requires a compatible ...
The Ultra HD Forum defines a wide color gamut (WCG) as a color gamut wider than that of BT.709 . [17] Color spaces with WCGs include: Rec. 2020 – ITU-R Recommendation for UHDTV [18] Rec. 2100 – ITU-R Recommendation for HDR-TV (same chromaticity of color primaries and white point as Rec. 2020) [19] DCI-P3; Adobe RGB color space; DxO Wide Gamut
The first CRT television sets were manufactured in 1934 and the first color CRT television sets were manufactured in 1954. [ 4 ] [ 5 ] The term "standard-dynamic-range video" was adopted to distinguish SDR video from high-dynamic-range video (HDR video), a new technology that was developed in the 2010s to overcome SDR's limits.
The CIE color spaces were created using data from a series of experiments, where human test subjects adjusted red, green, and blue primary colors to find a visual match to a second, pure color. The original experiments were conducted in the mid 1920s by William David Wright using ten observers [ 3 ] and John Guild using seven observers. [ 4 ]
