The CIE 1931 color space standard defines both the CIE RGB space, which is a color space with monochromatic primaries, and the CIE XYZ color space, which is functionally similar to a linear RGB color space, however the primaries are not physically realizable, thus are not described as red, green, and blue. M.A.C. is not to be confused with MacOS.
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%.
A color space in which the perceptual difference between colors is directly related to distances between colors as represented by points in the color space, i.e. a uniform color space. [12] [13] A color space in which colors are unambiguous, that is, where the interpretations of colors in the space are colorimetrically defined without reference ...
YIQ is the color space used by the analog NTSC color TV system. I stands for in-phase, while Q stands for quadrature, referring to the components used in quadrature amplitude modulation. Other TV systems used different color spaces, such as YUV for PAL or YDbDr for SECAM. Later digital standards use the YCbCr color space.
The ′ ′ color space is rotated relative to the difference signal color space, such that orange-blue color information (which the human eye is most sensitive to) is transmitted on the ′ signal at 1.3 MHz bandwidth, while the ′ signal encodes purple-green color information at 0.4 MHz bandwidth; this allows the chrominance signal to use ...
Y′UV, also written YUV, is the color model found in the PAL analogue color TV standard. A color is described as a Y′ component ( luma ) and two chroma components U and V. The prime symbol (') denotes that the luma is calculated from gamma-corrected RGB input and that it is different from true luminance . [ 1 ]
The resulting BT.709 color space is almost identical to that of the BT.601-6 used by PAL and SMPTE C, and covers 35.9% of the CIE 1931 color space. [19] It also covers 33.24% of the CIE 1976 u’v’ space [ 20 ] [ 21 ] and 33.5% of the CIE 1931 xy diagram.
The derived color space specified by x, y, and Y is known as the CIE xyY color space and is widely used to specify colors in practice. The X and Z tristimulus values can be calculated back from the chromaticity values x and y and the Y tristimulus value: [ 15 ]
