Kelvin is a measurement unit used to measure the color temperature of light.
What are the attainable examples of these color temperatures? At a higher temperature, the color is expressed as light (cool) blue. With a lower temperature, the color is expressed as a (warmer) yellow-red color.
Below, you will find certain examples:
| Candle light | 1200K |
| Sunrise (Morning) | 2000K |
| Sunrise (High noon) | 3500K |
| Daylight | 5000K |
| Afternoon sun | 5700K |
| Neutral white light | 6500K |
The color temperature has a great impact on the overall atmosphere of a room. Warmer/darker light for instance will have a calming effect on the brain, while a blue/sharper light enhances your concentration.
