Template:Color temperature/doc

{{Color temperature}} returns the color of a black body at a desired temperature. A polynomial approximation over reciprocal temperature is used. The exact formula is specified in Module:Color temperature.

Use

Template expects a temperature greater than or equal to     800 K. Color is automatically labeled with the temperature unless the parameter text is filled. hexval tag can be used to return only an hexadecimal color code.

  • Color space : sRGB
  • White point : D65
  • Gamma : 2.2

Warning

  • Each color use the maximum peak luminance available on the screen because lightness variations of a black body are too high to be displayed on a regular display device.
  • Colors below     1,900 K are out of sRGB gamut. White had to be added (relative colorimetric mapping).
  •     800 K is the minimum value because it is the Draper point, where black-body radiation starts to become visible to the human eye.
  • The clause class="mw-no-invert" is necessary for use in tables in order to display correctly in dark mode.

Demo

Display color temperature

{{Color temperature|3400}} returns     3,400 K

Customize label

{{Color temperature|1850|text=Candle light}} returns     Candle light

Return hexadecimal code

{{Color temperature|6500|hexval}} returns fff8fe.

{{Color temperature|5000|xy}} returns 0.31350353, 0.32359593.
