Lilac is OPI - Lucky, lucky lavender. Yes, I know that name of this polish does not match name of the flower of the title...
Green is Color Club - La petite Mint-sieur. I did gradient on my ring finger using this two colors, and then on the lilac part I reverse stamped some mint leaves, or at least I call them mint leaves. For them I used Pueen -33 plate and Sally Hansen - Jumpin' jade and La petite Mint-sieur. On my pinky I did mint background, and then I attempted to paint lilac bloom with 3 different purple shades. How successful I was, it is for you to judge. At the end, I was not disappointed with results. It does not happen often that what I envision, I actually transfer onto my nails successfully.
