Template:Color temperature/doc

{{Color temperature}} returns the color of a black body at a desired temperature. A polynomial approximation over the mired is used.

Use

Template expects a temperature between     837 K and     1,000,000 K in first parameter. 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.

Recommended display

• 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     1,934 K are out of sRGB gamut. White had to be added (relative colorimetric mapping).
•     837 K is the minimum value because it returns pure red color in sRGB color space.
