  2. Standard illuminant - Wikipedia

    en.wikipedia.org/wiki/Standard_illuminant

    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.

  3. Template:Color temperature white points - Wikipedia

    en.wikipedia.org/wiki/Template:Color_temperature...

    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]

    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

  5. White point - Wikipedia

    en.wikipedia.org/wiki/White_point

    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 ...

  6. CIELAB color space - Wikipedia

    en.wikipedia.org/wiki/CIELAB_color_space

    CIELAB is calculated relative to a reference white, for which the CIE recommends the use of CIE Standard illuminant D65. [1] D65 is used in the vast majority of industries and applications, with the notable exception being the printing industry which uses D50.

  7. Color temperature - Wikipedia

    en.wikipedia.org/wiki/Color_temperature

    Common monitor color temperatures, along with matching standard illuminants in parentheses, are as follows: 5000 K (CIE D50) 5500 K (CIE D55) 6500 K ; 7500 K (CIE D75) 9300 K; D50 is scientific shorthand for a standard illuminant: the daylight spectrum at a correlated color temperature of 5000 K. Similar definitions exist for D55, D65 and D75.

  8. CIE 1931 color space - Wikipedia

    en.wikipedia.org/wiki/CIE_1931_color_space

    Thus the CIE 1931 Standard Observer function is also known as the CIE 1931 2° Standard Observer. A more modern but less-used alternative is the CIE 1964 10° Standard Observer, which is derived from the work of Stiles and Burch, [9] and Speranskaya. [10] For the 10° experiments, the observers were instructed to ignore the central 2° spot.
