The hair dresser used Color Charm on me for years, so when I started doing my own hair I used Color Charm with his exactly recipe. I was lucky because my hair dresser was a little dingy- he relied on me to tell him what to do with my hair color, half 6 and half 7 with equal about of developer and some cheap hair conditioner to keep hair soft. The conditioner in the mix really helps out, I use about a 2 tbsp after measuring the color and developer. It looks as good as when he did it.
