Galaxy S5 :: Bright White Backgrounds

Is there a way to make apps and other screens with a bright white background have a dark theme instead? It's much easier to read white text lettering on a dark background. For example, the phone dialer is bright white, but I want it dark like the older android versions.

I have Alliance ROM installed on a rooted S5 and am wondering if there is a dark UI theme in the settings somewhere. The 17 themes it comes with doesn't actually make the phone dialer dark. I'm seeing screenshots online of Alliance that are nice and dark (I think it's called Black Glass?), including the phone dialer. How do I get the whole android theme dark.

Same thing with other apps. There's a few local TV news apps that have a bright white background that I wish I could customize to a dark theme. The Samsung Music Player is bright white as well.
