Oooh thanks, this is awesome feedback! You're right that we wanted the color elements to be unobtrusive, but if it's turning out blurry for you, that's something we need to fix (you're probably not the only one affected, at that).

I've done some tweaking of the colors, and the tweaks are all now live on the site, so I hope that's more distinct (while still being unobtrusive). Please don't hesitate to let me know if you're still having trouble with the contrast!
