Everyone's bemoaning the fact that Color only works with those within 150 feet of you—and as it's such a new app, that's next to no-one. Never fear though, because on day two of the app being available, they're working on making it less "lonely." Two important changes are going to feature in the next update—namely, the distance will change for someone's photos to pop up on yours (it'll be a smaller distance in denser areas), and you won't be able to use the app if no-one's within that area. Locked out, dude. [Mashable]
