I'd say she's blue. Not turquoise.
I can't really see her wings though and if she were turquoise that's mostly where the greener colors would accumulate. (They also accumulate on the forehead, but I don't see anything there.)
Is she a DNA female? How old is she? She still has baby eyes. Sometimes the turquoise birds get greener over time.
Edit: Forgive me, you mention in your other thread she is DNA female and 2 months old.
If you can take a flash photo of her from behind and post it, I can tell you if she's blue or turquoise.
