Nope, never made it home...anyway, the easiest why would be to use Redshift directly. For example: redshift -b 0.8:0.1 -l 8:50 -t 6500:6500. This will keep the color temperature as is, but dim the monitor from 0.8 during the day to 0.1 during the night. Of course, swap out the location for your own. This has the upside to adjust automatically when it comes to time of day, instead of having to calculate that in a script.
