It's really hard to estimate how a product to be successful in Silicon Valley. Take Google+ example, what's so novel about it? Nothing, i must say. Twitter integrated with Disqus by your address book. But first they get good reviews, and use old tactic of invitation only system like gmail.

As a weak social creature myself, i find the Color app idea very interesting. I eager to find someone take photo in the place i am in. I constantly open and refresh if someone took but none i find. Why nobody is using it? I remember once showing the app and its idea behind to my friend and he also find it very curios and love it. But where are the users?

Press takes what it wants, don't rely on them. They may interest in your investment or office furniture or whatever they want. Press might dumb your app almost instantly, but you have to respond to criticism very early. However, i see no app updated since months i guess.

Here is the road map for a loving user: bucket all criticisms that made to Color. prioritize according to who made them, their power in press/social media. change UI, revamp and go to real events. go to all Geek conferences after parties, music festivals and shout your app. This app needs on the ground fight not online tech bloggers.
