My vote is purple bonsai. I would only be able to give a best answer in person. From what I know..
The GARF* purple bonsai is only 2 colors
The Valida (tri-color) would have 3 colors - purple/blue tips, posiibly have some tan or white at the visible base
I wouldn’t use the term GARF when you sell it, if you didn’t knowingly purchase it as such. I’d be comfortable using Purple Bonsai or just Purple & Green Acropora
