F.lux should let you customize hours
I work scattered hours and I love to come home at midnight and unwind with my laptop. Sometimes, I'll be home watching videos with my wife around 7 or 8 and everything is orange. I dont want to keep disabling it every hour, but I also dont want it off for the whole day. Can't there be a setting so I can make it run from, say, 11-1 instead of simply "day" and "night"?
Maybe in the future. For now, just change 'At night' to 6500K until you're ready for it to be warmer. When you're ready, switch it to your preferred color temperature.
