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.
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 Studio lamps, photofloods, etc. 3350 K

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 ...
The mired value associated with a given color temperature is computed as the reciprocal of the color temperature, in Kelvin, multiplied by : M = 10 6 T {\displaystyle M={\frac {{10}^{6}}{T}}} The shift is the difference in the mired values of the film and light source.
Colour temperature is important in the fields of image projection and photography, where a colour temperature of approximately 5600 K is required to match "daylight" film emulsions. In astronomy , the stellar classification of stars and their place on the Hertzsprung–Russell diagram are based, in part, upon their surface temperature, known as ...
