Use the supplied test profiles to check that your profiles are being applied correctly to your screen.

# How do I test if color management is working correctly?

The effects of a color profile are sometimes subtle and it may be hard to see if anything much has changed.

GNOME comes with several profiles for testing that make it very clear when the profiles are being applied:

# Blue

This will turn the screen blue and tests if the calibration curves are being sent to the display.

Åbn Aktivitetsoversigten og begynd at skrive Farver.

Click on Color to open the panel.

Select the device for which you want to add a profile. You may wish to make a note of which profile is currently being used.

Click Add profile to select a test profile, which should be at the bottom of the list.

Press Add to confirm your selection.

To revert to your previous profile, select the device in the Color panel, then select the profile that you were using before you tried one of the test profiles and press Enable to use it again.

Using these profiles, you can clearly see when an application supports color management.
