Night Shift Mode in macOS Sierra 10.12.4

The f.lux effect never looked as nice as the one on Android though - it looks like it just paints over another layer of orange color instead of removing the blue components when rendering. It makes my eyes hurt in the evening in a way that the night mode on my Pixel never does :/

Also it kicks in and gets really strong hours before I go to sleep.

Hopefully Apple themselves will do it better.

As far as I know only Android >=7 on hardware with a HWC 2 implementation support colour transforms [0], so all Android apps implementing a f.lux-style thing do exactly that, draw an orange rectangle over the screen.

F.lux on desktop has always worked that way though, I think. It should essentially be rendering the blue component substantially darker (up to removing it, depending on the temperature setting), instead of alpha blending with orange.

F.lux has no way to do this correctly on Android.

Luckily, since there was a lot of positive feedback to the implementation of this feature in the 7.0 preview, it has been backed at the driver level for 7.1.

Now the feature works perfectly and has no performance impact.

It also opens the door to a wide array of other modifications :

-color adjustements

-temperature shift

- color-blindness compensation

Basically you can apply any matrix you want on the screen output.
