It's too bad. Looks like Color is going down. Their initial idea of "location based social networks" (through the use of mobile phone data) would have been much more profitable in the long run and probably lead to some interesting services. Their initial execution sucked but their "big idea" had potential.
Actually, I expect every Color pivot (including this one) to be a trojan horse to execute the original big idea. The invite mechanism via FB is still "take a picture" and post to FB, so the implicit network is still being built.
The truth to the question "what problem does this solve?" is a constant for this company: "this" solves our problem of trying to get a critical mass of users to take metadata-rich pictures all over the world.
