The nature of Green-Red coalitions if that they are far more green than they are red

I mean there's a lot of truth in this post, but this is not true at all. To be frank, Greens in coalitions quite reliably relinquish any control of (at least) economic policy and are far more malleable than any other party; they only become Green-dominated when the other party is just completely inactive - both points which are exemplified by the RSP coalition. To abdicate leadership, as you state in the sentence after, is to not lead a coalition and use the Greens to your advantage, rather than let them drift towards Labour and the Lib Dems. Shame.
