The problem with OS-provided facilities for this is that they often don't give you enough control. I still use f.lux on an Android phone that I rooted specifically for this purpose, because that's the only way I can get dark red on black text in Kindle (for night reading).

I used to use f.lux on Android until I found "Twilight"

Twilight doesn't do the same thing. It, and all other screen filters on Android that do not require root, can only add color, not subtract it. Thus, it cannot make white text on black background into red text on black background - it can only make it into pink text on red background.
