Colour Information Chart

Colour variation in lighting is known as “colour temperature” and is measured in degrees Kelvin. The colour temperature scale ranges from at one extreme a candle flame (approximately 1,900K) to a deep blue sky (approximately 10,000k). The chart below illustrates a number of key lamp types and where they appear on the colour temperature spectrum.
