Hi Im probably going to be buying your ancient blue product in the next week or so. However I wanted my main canvas to be my girlfriend and Im not sure if her skin is too dark to use indigo on. The lighter parts of her body Im not too worried about, but the darker parts range from http://en.wikipedia.org/wiki/Old_Gold to http://en.wikipedia.org/wiki/Dark_goldenrod . If it is infact too dark I might just stick to henna for her and use indigo for myself.
