But that's just making the observation that things that may seem obvious at first glance may not be obvious once you think more deeply about them. It doesn't really matter why they are not obvious. What matters is that they are not obvious.
Good point, and thank you for the clarification. I had been interpreting "manifestly not obvious" as a rhetorical device to state that the board were clearly decided and set that shutter-colors were within the scope of what an HOA board might reasonably decide, and therefore it is "manifestly not obvious" that it is outside the scope. (Sort of how somebody saying the words "There are some here who may disagree with you." is implicitly stating that they disagree and is inviting others to join in disagreement.)
I agree that it is not obvious where the line is, and was attempting to a hypothetical where even a single person might be unsure.
