I've had 7 laser treatments, my first 6 were Revlite and my 7th was an Enlighten. Is my tattoo oxidizing? (photos)

I've had 7 laser treatments. She was supposed to be pale and the artist made her orange. I need to get her skin as light as possible so my new artist can fix it. It's turned a greenish/gray though. My first 6 treatments were with a Revlite and my 7th was an Enlighten with 1064 and 532 wavelengths in the same treatment. It's been 3 months. Should I do one more treatment with the 532 which is good for yellow and orange? Is it oxidizing because he used some white? Any advice is appreciated.
