This might be a good time to point out that they could have built the same app for a tiny fraction of the amount spent. If they had done that, they'd still be moving down the road looking for traction.
Here is what I don't agree with in this statement, you take the app they shipped and the money they raised and you then assert they could have done it for so much less.
The flaws in that claim are that the shipped application is probably not particularly close to the 'vision' of what they wanted it to be, no doubt it was a minimum viable product to test the basic concept, and you and I don't really know how much money they spent, we know how much they raised, they could have most of it still in the bank, less real estate and salary costs.
I don't think there was anything at all wrong with the color "concept" or what they were trying to achieve. The two things that failed were; they raised too much money and their management collapsed.
Raising too much money is a well known risk for serial entrepreneurs, after a few 'hits' you find a lot of people want in on your next project. (apparently this is true in Hollywood too but I've no personal experience with that). The 'right' thing to do is get your minimal funding and move on, use the extra leverage to improve the term sheet, not get more money. Rule #1 for any startup is have a plan for every single dollar you raise.
I can assure you that even if they had the printing money [1] product having that much dysfunction at the top level is going to kill it dead. Further its really impossible to ship something if your leadership isn't at least somewhat aligned and sharing the same goals. That is particularly true of the CEO. As its one of the CEO's primary responsibility to guide the train to its destination, if they are compromised the train stops. That is what you have a board of directors, having only the overall success of the company as their motivation they are supposed to recognize this and toss the CEO. Say what you want about Yahoo's board but they certainly have the 'fire the CEO' process down.
Color was a spectacular failure, but not because the app they shipped could have been shipped for less, rather their failure is that they executed so poorly against their original vision.
