Well, that's interesting if Facebook server fails to deliver you the javascript API files, Color.com will only display you an empty page. Their application initial load depends at a 100% on an external website on which they have no control. If facebook has a downtime for that file, nobody can load their application. That's sounds like an awful idea.

Thanks for noticing. Yes, my adblock is configured not to allow facebook to get my surfing data. Disabling allows color.com to open on FF just fine.
