Colour temperature

What is the difference between warm and cold light?

The color temperature of a light source is usually stated in kelvin (K) and the scale follows the temperature of an ideal black body that emits light in a color tone comparable to the light source.

If the color temperature is above 5000K for a light source, the light is considered to be cool, and if the color temperature is between 2700-3000K, the light is considered to be warm .

High color temperature (cold light) glows blue-white and low color temperature (warm light) glows more yellow or reddish.​

The color temperature is important both for the working environment and for the color reproduction. A cold light can be perceived as unpleasant to work in for a longer time and for painters it can be important to be able to evaluate surfaces in different color temperatures.
