Can I get notified when my color profile is inaccurate?

You can be reminded to recalibrate your devices after a specific period of time. Unfortunately, it is not possible to tell without recalibrating whether a device profile is accurate, so it is best to recalibrate devices regularly.

Some companies have very specific calibration expiry policies for profiles, as an inaccurate color profile can make a huge difference to an end product.

If you set the timeout policy and a profile is older than the policy then a red warning triangle will be shown in the Color panel next to the profile. A warning notification will also be shown every time you log into your computer.

To set the policy for display and printer devices, you specify the maximum age of the profile in days:

$ gsettings set org.gnome.settings-daemon.plugins.color recalibrate-printer-threshold 180
$ gsettings set org.gnome.settings-daemon.plugins.color recalibrate-display-threshold 90
