Color temperature

Color temperature is the expression of energy levels of light sources in Kelvins (K), based on the notion of a perfect absorber which changes color dependent on the temperature it is heated to.

Lower color temperature ratings correspond to the emission of more yellow light, whereas higher color temperature ratings are associated with a more blue light. Consequently, the color temperature of a light source is indicative of the levels of certain colors of light it emits.
