How to change screen color temperature in Kubuntu (KDE)

Kubuntu integrates the KDE desktop environment, which includes the Night Color feature to adjust screen color temperature. This feature reduces blue light emissions and creates a warmer display, helping to minimize eyestrain during prolonged usage.

Night Color provides customizable temperature settings and scheduling, allowing adjustments based on personal routines or local sunrise and sunset data. This fine-grained control enhances viewing comfort, especially in low-light conditions.

System Settings serves as the central hub for all Night Color configurations. By selecting a desired color temperature and schedule, users can align display behavior with personal preferences, environmental factors, and daily habits.

1. Open System Settings from the application launcher.
2. Click on Display and Monitor on the sidebar menu.
3. Go to Night Color configuration panel.
4. Click on Activate Night Color checkbox to enable Night Color.
5. Slide to set the color temperature.
6. Click on the Activation Time select list.
7. Select or set the time period to enable Night Color.
8. Click on the Apply button to activate and save the configuration.
