Correct! We can introduce a timing to it, and say that the next day there would be nobody who had figured out their eye color by the morning meeting of the tribe. But the day after, etc., your answer comes into play. Given that view, how long will the tribe survive?

No, we can assert that they all know brown and blue are the only possibilities. The bad stuff still occurs even if this is assumed by the tribe.
