To the best of my knowledge, Orchid was going to get a color 10 with her Ultimate Source figure when they launched the season 2’s (TJ Combo, Orchid and Cinder). Those figures were actually shown off in prototype form, however since those figures were never released, no one really has access to Orchid’s color 10.
That’s not to say that no one has it at all. I’ve seen in-game pictures of it, but I’m pretty sure those pictures are from Ultimate Source themselves. If any players have them, my guess is the number is extremely small. Maybe a few pro players somehow got it from Ultimate Source. Who knows.
For anyone else that’s curious, here’s a link to a previous discussion about it which shows a picture:
