In this case, I'm fairly certain they mean both Tumblr and Twitter; since the background for the sites' logo/icon thing is blue, they're strongly associated with that color. Tumblr in particular is known as a "blue hellsite" by its userbase, and while I can't say I've been on Twitter long enough to notice anything similar, it wouldn't surprise me.
