Her Pirouette Forme colors are identical to those of a typical Meloetta.

So, a bit of backstory. Olive was born as a sort of clone of Melia. Melia had two different personalities: a calm one and a rash one. However, it got to the point where the rash one never got to see the light of day again, and Melia didn't want to permanently lose that part of her. Her aunt was able to make something to split Melia into two individual beings, both with one of her personalities. The original Melia kept her calm side, whereas her "clone" (Olive) took her rash side.

As a side effect of this character split, I will no longer be using this color for Melia's text, instead using this color for it. Olive will be using this color for her text.
