I just bound it to 5 keyboard shortcuts to switch between off, 5000K, 4200K, 3400K and 2500K. During the day I just pick whichever matches the ambient light, which one feels best or is required for current activity. (In practice I do not use the 2500K setting) Maybe I'm unique but I never liked how F.lux on Windows made the transitions slow, and automagically based on what the sun is doing, which approximates but often does not quite align with the ambient light in a room, let alone pick up on my fickle personal preferences of just how orange-pink I like my monitor to be at any moment. Edit to add: This method uses no config files. I just apt install redshift and use keyboard settings to bind shortcuts to commands `redshift -x`, `redshift -O5000`, `redshift -O4200`, etc.
