What is Correlated Colour Temperature (CCT)?


This is the colour of the light and is measured in degrees Kelvin (K). The lower the number the warmer the colour. As it increases the white light becomes colder. Most paintings benefit from Warm White light, specifically 2,700K, however, this is not always the case. Examples of the ranges are detailed below:

1,800K Candle Light

2,000K – 2,400K Extra Warm White

2,700K – 3,200K Warm White

3,600K – 4,200K Natural White

4,600K – 5,500K Cool White

5,600K – 6,400K Daylight White

6,600K – 7,500K Ultra Daylight
