But for Chrome, I just started using 'Hacker Vision' extension and it seems to work nicely: https://chrome.google.com/webstore/detail/hacker-vision/fommidcneendjonelhhhkmoekeicedej/details?hl=en-US

I also have the 'Nicer Inverter' extension running simultaneously (https://chrome.google.com/webstore/detail/nicer-inverter/oichlckdgnbjkmhaebnnhibamjgpndkm?hl=en-US) -- this is actually my primary (always running) extension. I run 'Hacker Vision' for pages that 'Nicer Inverter' doesn't work on, e.g., Codeacademy.com).

Just thought it was a worthwhile tip to share with my fellow hackers. Save your eyes!
