 | | The colour of light -the difference between warm and cold The colour of light makes the difference between cold and warm light. It is determined by the colour spectrum, and this varies according to the type of lamp. The colours red and blue are of major importance. The higher the red component in the light, the warmer the light, the more blue in the light, the colder it will be. The colour of light is measured in Kelvin (K). | | ||||
