Color seems like one of those ideas that would be pretty rad if 1 million people already used it. Because no one has the app yet, if you fire it up it's totally blank. You take a picture of yourself, post it, then the rest of the UI is whitespace. There's nothing to look at or do. It's possibly the worst first-run user experience I've ever seen.
I wonder if the Color engineers were always using the app together and always seeing each other's photos. If that's the case the UI was always full of stuff to look at, and they probably demoed it to journalists like this as well. Did they ever actually see the app as an empty slate like everyone will see it the first time they use it? My guess is: no.
