What is the light colour and colour temperature anyway?
Colour temperature (CT) is the degree of warmness or coolness of a light source. It will change from the different type of bulbs, different materials and different lamp coverage.
The colour temperature measured in Kelvin degrees (K), if the Kelvin degree is low that means the light colour is more like a warm white. If it’s high, the light colour is more like daylight white. In our daily life, the common ranges of colour temperature of a light source are from 2700k to 6500k. The light colour within that range can be classified as warm white, neutral white and daylight white.
For other environments such as industrial lighting and car lighting, the colour temperature can be more than 7000k. When the colour temperature is higher than 6500k, the light colour of it is cold light.
