The CIE positions D65 as the standard daylight illuminant: [D65] is intended to represent average daylight and has a correlated colour temperature of approximately 6500 K. CIE standard illuminant D65 should be used in all colorimetric calculations requiring representative daylight, unless there are specific reasons for using a different illuminant.
A list of standardized illuminants, their CIE chromaticity coordinates (x,y) of a perfectly reflecting (or transmitting) diffuser, and their correlated color temperatures (CCTs) are given below. The CIE chromaticity coordinates are given for both the 2 degree field of view (1931) and the 10 degree field of view (1964). [1]
Apple Inc developed displays using the P3 primaries, and the corresponding Display P3 color space. [17] [18] While it uses standard P3 RGB primaries, the white point is D65 instead of the DCI ~6300 K white point. The D65 white point is the existing standard for common sRGB and devices (Adobe RGB also uses D65).
English: An SVG representation of the D65 illuminant spectrum plotted in 1 nm increments, based on the values specified in Table B.1 of the ISO CIE 11664-2-2022 standard. Date 10 September 2023
An illuminant is characterized by its relative spectral power distribution (SPD). The white point of an illuminant is the chromaticity of a white object under the illuminant, and can be specified by chromaticity coordinates, such as the x, y coordinates on the CIE 1931 chromaticity diagram (hence the use of the relative SPD and not the absolute SPD, because the white point is only related to ...
RGB color spaces is a category of additive colorimetric color spaces [1] specifying part of its absolute color space definition using the RGB color model. [ 2 ] RGB color spaces are commonly found describing the mapping of the RGB color model to human perceivable color, but some RGB color spaces use imaginary (non-real-world) primaries and thus ...
A comparison between a typical normalized M cone's spectral sensitivity and the CIE 1931 luminosity function for a standard observer in photopic vision. In the CIE 1931 model, Y is the luminance, Z is quasi-equal to blue (of CIE RGB), and X is a mix of the three CIE RGB curves chosen to be nonnegative (see § Definition of the CIE XYZ color space).
English: The visible gamut plotted within the CIEXYZ color space. a and b are the horizontal axes. L is the vertical axis. L is the vertical axis. Uses D65 whitepoint.
