Color launched to a fair amount of fanfare back in March, and it's not surprising, really -- the company was spearheaded by Lala founder Bill Nguyen, with ten of millions in backing from some top venture capital firms. The hype surrounding the photo-sharing app didn't take long to die down, however -- over the past several months, we haven't heard much from the startup. Turns out the Color team was rethinking the project from ground up. The company used f8 this week to launch a new version of the app built entirely around Facebook. The new Color harnesses updates to the social Network's Open Graph protocol to introduce the concept of "visits," a social gesture that prompts a user to request a live video feed from a Facebook friend upon seeing an interesting photo in their feeds on the social network or in the iPhone / Android app. The brief video stream can be attended by multiple users, becoming something of a mini UStream built into Facebook. The new Color is currently in a closed testing phase, though interested parties can sign up to take part below.
