The first swatch is permanent 60g of 6N with 20-volume developer, processed for 35 minutes.
The second swatch is the same formula with 6g of green concentrate. This is best when you want a soft ash result meaning not all the warmth is neutralized. It’s very good on lighter brown salt and pepper hair.
The third swatch is the original formula with 3g of green concentrate + 1.5g (1 and 1/2 inch) of blue concentrate. It’s best when you want ash with almost no warmth coming through.
The fourth swatch is the original formula with 3G of blue concentrate. This gives smokey a result that is best for darker brown hair with little gray.
