Choose Your Desired Ambience or Activity The colour characteristics of light are often described in terms of what is called “colour temperature” – usually either warm (yellowish) or cool (bluish), with the temperature measured in degrees of Kelvin (K). The higher the number, the cooler the light. Low colour temperature is best for recreational activities and socialising. High colour temperature and intensity are best for concentration.
