Detect user change of color and light status for automation


I have some light automations that use circadian lighting to change the color and intensity of the lights in my home automatically. Works great, really nice automation.

Sometimes my girlfriend wants to change for example the colour of a light in the livingroom. I would like to detect that in this case a user made a change to the colour and/or intensity and pause the automation for a while. How could I detect such a user change and how to distinguish it from changes made by automations?
