Opposites again

In a (still unpublished) discussion a while back, of the complexities of the idea of “opposites”, I said:

"Opposite" extends to all sorts of situations in which logic doesn't apply. Red is the opposite of green, but I'm not sure that it makes sense to ask for the logical negation of green. I suppose you can go with "not green", which is certainly quite different from "red".

A related example: Red is the opposite of green.

What's the opposite of “not green”? Is it “not red”? I think it isn't. The opposite of “not green” is “green”.
