Actually ‘green great dragons’ could exist, but the phrase is not a synonym of ‘great green dragons’. There would have to be a class of thing called ‘great dragons’ – perhaps distinct from ‘lesser dragons’ – and some of those might be green. Hence, ‘green great dragons’ or ‘green Great Dragons’.
But the point is still correct. It’s better visualized in Venn diagrams or syntactic parsing, though.
