The colour of light is expressed in Kelvin. So we are actually talking about the colour temperature.
What are tangible examples of this colour temperature? At a high colour temperature, the light becomes bluer (cooler), at a low colour temperature, the light becomes yellower (warmer).
Below are some examples.
| Candlelight | 1200K |
| Sunrise | 2000K |
| Sunrise after 1 hour | 3500K |
| Daylight | 5000K |
| Midday sun | 5700K |
| Neutral white light | 6500K |
The colour temperature has a great influence on the atmosphere in the room. Warm light makes you calmer, and blue light increases concentration.
An overview of our colour temperatures:
| Flame | 2200K |
