Most I've seen from rose/rainbow variant bubble tips have white undersides, this is the first time seeing one with green undersides. When it's balled up it is completely green.
The last two pics are the same, I've messed with the last pic to give it more pop.
That morph is the second most usual in Sweden after the pure red. There are so many different colors and they can change a little too depending on how they are cared for. I have had this morph in a tank with many pure red and it lost the green after a few months.
