correlated color temperature
CCT is given in kelvin (the SI unit of absolute temperature) and refers to the appearance of a theoretical blackbody heated to high temperatures. As the blackbody gets hotter, it turns red, orange, yellow, white, and finally blue. The CCT of a light source is the temperature (in K) at which the heated blackbody matches the color of the light source in question.
