  2. Color temperature - Wikipedia

    en.wikipedia.org/wiki/Color_temperature

    The color temperature scale describes only the color of light emitted by a light source, which may actually be at a different (and often much lower) temperature. [1] [2] Color temperature has applications in lighting, [3] photography, [4] videography, [5] publishing, [6] manufacturing, [7] astrophysics, [8] and other fields.

  3. Correlated color temperature - Wikipedia

    en.wikipedia.org/wiki/Correlated_color_temperature

    Before the advent of powerful personal computers, it was common to estimate the correlated color temperature by way of interpolation from look-up tables and charts. [18] The most famous such method is Robertson's, [ 19 ] who took advantage of the relatively even spacing of the mired scale (see above) to calculate the CCT T c using linear ...

  4. 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]

  5. Chromaticity - Wikipedia

    en.wikipedia.org/wiki/Chromaticity

    The CIE 1931 xy chromaticity space, also showing the chromaticities of black-body light sources of various temperatures, and lines of constant correlated color temperature 3D chromaticity diagram of the WideGamutRGB color space. Chromaticity is an objective specification of the quality of a color regardless of its luminance.

  6. Visible spectrum - Wikipedia

    en.wikipedia.org/wiki/Visible_spectrum

    Spectroscopy is the study of objects based on the spectrum of color they emit, absorb or reflect. Visible-light spectroscopy is an important tool in astronomy (as is spectroscopy at other wavelengths), where scientists use it to analyze the properties of distant objects.

  7. Standard illuminant - Wikipedia

    en.wikipedia.org/wiki/Standard_illuminant

    This is by design; the XYZ color matching functions are normalized such that their integrals over the visible spectrum are the same. [1] Illuminant E is not a black body, so it does not have a color temperature, but it can be approximated by a D series illuminant with a CCT of 5455 K. (Of the canonical illuminants, D 55 is the closest.)

  8. Planckian locus - Wikipedia

    en.wikipedia.org/wiki/Planckian_locus

    Planckian locus in the CIE 1931 chromaticity diagram. In physics and color science, the Planckian locus or black body locus is the path or locus that the color of an incandescent black body would take in a particular chromaticity space as the blackbody temperature changes.

  9. CIE 1960 color space - Wikipedia

    en.wikipedia.org/wiki/CIE_1960_color_space

    The Planckian locus on the MacAdam (u, v) chromaticity diagram. The normals are lines of equal correlated color temperature. The CIE 1960 color space ("CIE 1960 UCS", variously expanded Uniform Color Space, Uniform Color Scale, Uniform Chromaticity Scale, Uniform Chromaticity Space) is another name for the (u, v) chromaticity space devised by David MacAdam.
