Does Facebook copyright "white text on blue background"?

I absolutely get the craziness of the claim. But given it's listed fifth of five claims they take issue with (others being outright trademark infringement,) I imagine they really only care about it in congruency with the others.

I doubt (hope?) that even a giant like Facebook would go after every person who uses lowercase white text on a blue background.

(That said, I've never used the app in question. I'm assuming the other claims, not referenced in the post, have a ring of truth?)

But they won't sue every person, this applies only in the context of a facebook-related app, which is probably not completely unreasonable to ask

Reading the article, clearly they're trying to prevent confusion between facebook api apps and facebook. So no. flagged for linkbait title.

Looks to me like they are paving the way for the Facebook iPad app by try to reduce any risk of confusion between non-official apps.
