  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

    The first verified the findings of Priest, [7] Davis, [8] and Judd, [9] with a paper on sensitivity to change in color temperature. [11] The second proposed a new chromaticity space, guided by a principle that has become the holy grail of color spaces: perceptual uniformity (chromaticity distance should be commensurate with perceptual difference).

    Color temperatures and example sources Temperature Source 1700 K Match flame, low pressure sodium lamps (LPS/SOX) 1850 K Candle flame, sunset/sunrise: 2400 K Standard incandescent lamps: 2550 K Soft white incandescent lamps 2700 K "Soft white" compact fluorescent and LED lamps 3000 K Warm white compact fluorescent and LED lamps 3200 K

  5. 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]

  6. Redshift (software) - Wikipedia

    en.wikipedia.org/wiki/Redshift_(software)

    Redshift can be used to set a single color temperature and brightness ("one shot mode") or can adjust the temperature and brightness continuously to follow the sun's elevation, in which case it will transition to the night color temperature settings near twilight. The temperature and brightness settings for daytime and night can be user-configured.

  7. Mired - Wikipedia

    en.wikipedia.org/wiki/Mired

    In photography, mireds are used to indicate the color temperature shift provided by a filter or gel for a given film and light source. For instance, to use daylight film (5700 K) to take a photograph under a tungsten light source (3200 K) without introducing a color cast , one would need a corrective filter or gel providing a mired shift

  8. High-CRI LED lighting - Wikipedia

    en.wikipedia.org/wiki/High-CRI_LED_lighting

    CRI is calculated from the differences in the chromaticities of eight CIE standard color samples (CIE 1995) when illuminated by a light source and by a reference illuminant of the same correlated color temperature (CCT), commonly measured in kelvins, indicating the light color produced by a radiating black body at a certain temperature; the smaller the average difference in chromaticities, the ...

  9. CIE 1960 color space - Wikipedia

    en.wikipedia.org/wiki/CIE_1960_color_space

    The CIE 1960 UCS does not define a luminance or lightness component, but the Y tristimulus value of the XYZ color space or a lightness index similar to W* of the CIE 1964 color space are sometimes used. [2] Today, the CIE 1960 UCS is mostly used to calculate correlated color temperature, where the isothermal lines are perpendicular to the ...
