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: 3500K
