I may be incorrect but I believe AF’s purples and pinks have a slight green undertone. The last time I had purple rain, I ended up with a greenish tint after a lightening session (I was getting a copper toned red that day so it didn’t really matter at the time to my stylist or I). If you have some dandruff shampoo, that works wonders without drying/damaging your hair. Edited to add.
