Do you think the green was mixed with yellow colour? And the yellow turned brown? Is this going to fade eventually?
Thank you for your question and the accompanying photos.Your green ink was probably compounded with titanium dioxide white, which oxidizes to that very familiar brown color, usually on the very first treatment. It is a common and expected result (I always suspect TiO2 lurking in light colors and prepare patients accordingly), and you can expect the brown to fade away nicely with continued treatment.Good luck!
