Light color temperature

You can define color temperature instead of color option in artificial light. By adjusting the light temperature, a much more real effect can be achieved than by changing the color of the light. The color temperature can be adjusted from 1000 K to 10000 K to simulate the light of today's light bulbs from a warm hue (reddish) to the cool hue (bluish).

Example: 

Warm white light (3000K) vs. colder light (4000-6500K).

Colder light (4000-6500K).	Warm white light (3000K)
