I like to scroll GH as it gets dark, and I'm just not a huge fan of artificial light (Read: I loves the darkness), and so my eyes adjust to the black and orange, which is great, until I change tabs to check my email, or facebook (who knows what I'm doing there) and I'm immediately BLINDED by the white backgrounds, which of course sends me to change tabs back immediately.
Was that the plan? Have our eyes adjust to GH, so we could never view another site?
