Firstly, gramatically correct would be "Die Grünen" (the greens) i.e. "Grüne".
Which would instantly connect us with this shitfest of a party advocating for peace and then doing the exact opposite, licking the US asshole, terminating our nuclear energy etc. etc. let's not go there here and now.
It makes zero sense as a word, just call us "Immers" though. Much better. I instantly think of Immelmann, which is the dude who invented the flying maneuver in WWI where you rise up, turn 90 degrees and swoop back down in a dogfight to turn the fight against your opponent.
