I’ve use Twilight for years and love the red filter for using my phone at night. But since getting an AMOLED screen it’s started to frustrate me. The way Twilight seems to work means that black also gets a red tint. Previously this was great, but on amoled black is completely dark with no back-light that needs masking with red. So by shifting it red, Twilight is actually making the screen much brighter.

Tldr: Any apps that leave black as black, but give a red tint to all the other colors?
