I doubt it's the color so much as it's "font-weight: 300;"... that's pretty thin. Removing that makes it a lot more pleasing to look at, in my opinion.

Thanks @Alupis. Got a tip for that internally as well. I just pushed the fix up with 400 instead of 300.

Awesome! It seems such thin and/or light fonts are okay to read on retina displays (which is where I assume they were tested) but not on other displays. I happened to be reading on a non-retina display.
