The directions say to use twice as much activating lotion to the color, so the color amount is half that of the activating lotion.

Well say that the hair color is a bottle of 2 oz. Then you would put the whole bottle of color in a bowl, and use 4 oz. of activating lotion. Those are just common amounts for hair color. Just modify that to what you need.

double the color amount

1oz color = 2oz activating

which is probably 5-10 vol peroxide
