"Night Mode" on Android 6.0.1

Hi all,
I'm Vincenzo from Italy. I searched alot for an application that could simulate "Night Mode" on Android 6.0.1, but no luck.

My request is simple: I noticed that on Xperia Z3 Compact, 6.0.1, I can change screen color. Can you create an app that has a decent graphic widget which could change from 0 to 255 red tone and viceversa? It could be useful for others Xperia devices! Or, if you can, this could be automated with sunset and sunrise of user position.

Sorry for my english, hope it's not a problem.

P.S. Image of the display color changer in attachment.
