Introducing f.lux

We're all in favor of more laptop use by candlelight. Well, Lorna and I are up late a lot using our computers, and we noticed that the monitors looked awful after dark. So a few months ago, we began our mission to fix that.

Your monitor looks like daylight (6500K). This is just fine during the day, but it looks pretty bad at night.

F.lux fixes this. Tell it where you are, and it makes everything better.

F.lux defaults to match halogen lights at night (3400K). Our alpha testers tell us that shutting this off feels like a "punch in the face", so be careful out there.

It works on PC and Mac. You won't notice anything until after dark.

Enjoy!

  3. It's actually pretty extreme, but I can add it to the mac version if people want to try it. Windows...doesn't allow it (because the blue component dips below 0.5!)
