The colour of light is expressed in Kelvin and in point of fact, we are talking about colour temperature.
What tangible examples can be provided for this colour temperature? At a higher colour temperature, the light becomes a deeper blue (cooler), whereas the light becomes more yellow (warmer) at a lower colour temperature.
Please refer to some examples below.
|Sunrise after 1 hour||3500K|
|Neutral white light||6500K|
The colour temperature has a great influence on the atmosphere in spaces. For example: warm light makes you quieter, whereas blue light increases your concentration.
Please refer to this overview of colour temperatures that Calex provides:
|Extra warm white||2100-2500K|
