- Color temperature to set at daytime/night
The neutral temperature is 6500K. Using this value will not change the color
temperature of the display. Setting the color temperature to a value higher
than this results in more blue light, and setting a lower value will result in
more red light.
Default values:
- Daytime temperature: 5500K Night temperature: 3700K
