Correlated Color Temperature (CCT)

Understanding the Color of light.

CCT or Correlated Color Temperature is the measure used to describe the relative color appearance of a white light source. CCT indicates whether a light source appears more yellow/gold/orange or more blue, in terms of the range of available shades of "white." CCT is given in kelvins (unit of absolute temperature).


2700K is "Warm" and 5000K is "Cool".


The typical light color we are used to in indoor home lighting is "warm", 2700 - 3200K.
