Twilight and Lux both contain naive implementations using a semitransparent overlay. The result of this that blacks and dark colors end up being brightened instead of left alone, as a proper color-temperature change would do. This looks bad on all screens, but especially so on AMOLED displays that support a true black.
Cf.lumen[1] is, I believe, the only Android app that can actually change the color temperature of the screen like f.lux can, but it requires root as well as installation of a special "driver" in order to do so. My guess would be that the "complicated install process" referenced by the f.lux devs is probably similar.

- tempestn 11y agoI believe if Lux has root access it changes its behaviour to also change the actual color temp rather than using an overlay.
- NoGravitas 11y agoIt does if you install either a plugin specific to your device, or a plugin to use CF Lumen as its backend.

- tripzilch 11y ago> And Cyanogenmod has a built-in color temperature changer anyway. Really? Cool! Where is it though? I just went through the settings and couldn't find anything but Display & Lights > Colour calibration, which just gives some R/G/B sliders (that don't even seem to do anything?) no colour temp, that I could find.
