What was Color's idea? I had heard of it at the time, including the talk about the high funding for what may have been a simple idea, but did not check (partly due to reading about it being overhyped, probably). Something to with color and photos?
Color was an "elastic" social photo network based on shared locations. Elastic meaning that instead of having binary "friends" and "non-friends," your friendship with people is was a algorithmic strength value based on how often you shared photos from the same location. (Which would map to how often you were together or at least at the same events, presumably mapping to how close you are in the present.)
Not to mention, the idea wasn't necessarily worthless. It wasn't any worse than, say, Instagram. We only remember it that way because Instagram succeeded and Color failed.
