A darker blog?

I’m considering changing my blog theme so that it’ll get a dark background. Having browsed through numerous design blogs and portfolios on the Internet (perhaps one more frequently than others), I’ve come to the conslusion, that images and graphics are simply best viewed on a dark background. It’s just a lot easier on the eyes, and the colors also stand out a lot more. On top of that, I’ve heard that having a darker website is less power consuming, thereby emitting less CO2. So if you see some weird colors on my blog in the future, it’s probably because I’m tweaking the theme. Firebug here I come!
