Google Nexus 6 :: Browsers - Change Webpage Background To Dark Screen With Sepia

The number one thing that frustrates me about most Internet Browsers is the inability to change the settings to have a black webpage background with white letters. White backgrounds are so hurtful on the eyes, especially with a big screen device like the N6. It's additionally a source of bigger battery drain to have bright white pages. Now, for those who remember, changing this used to be possible with the stock "Internet Browser" that came on the Android devices.

I currently use "UC Browser" due to it's ability to change the webpage background to a dark screen with Sepia-colored letters.

Are there any other Browsers that do this or present this ability? And I'm not talking about dimming the entire screen in a poorly implemented "Night Mode" (a correctly implemented one would completely switch the text/background without affecting images).

I'm constantly re-evaluating what I use and would love to have alternatives.

An additional bonus is the VERY strong built-in ad-blocking capabilities of "UC Browser". It completely blocks all injected ads. Go to AndroidCentral using Chrome and you'll see an injected box by "GoogleAdServices" pop-up at the bottom of your screen. The same page with "UC Browser" (with ad-blocking activated) shows nothing but the webpage. I like to have Ads blocked to save bandwidth/data usage, so that's an important feature. What Browsers (or specific extension) blocks these types of Ads (like the ones from Google)? I like Ghostery Browser for this but you can't export Bookmarks.
