This location-based setting sounds clever, but it&#x27;s a crappy idea if you live further north than ~60°N. Or do you want your screen to go red at 3pm and stay that way until  10am the next day when it&#x27;s winter? And then in summer it&#x27;s red from 2am to 4am?<p>I use CF.lumen on Android and Redshift on Linux and I have to regularly shift the fake locations I give them in order to have them do what I want. At least with Redshift on Linux I can script it...
