ESalon is supposed to be able to give you a custom color based on pictures and such. I'm not sure how much they can *really* tell from a picture, but I'm going to give it a shot. I want to stay as close to my natural color as possible for as long as possible. My great, great grandmother died in her 90's with hair the same color as mine. She never had a single white hair. I find that shocking as I started getting them so young myself, but it is nice to know that I'm not necessarily doomed to be all white at 45 or something.
