It sounds like we have similar hair in color and style. I had bangs for a hundred years (or else, it just seems that way LOL) and have finally grown them out because I was tired of stringy damp bangs on my face in the summer heat. Now I keep my hair in a shoulder-length side-parted bob type style. Anyway, after wishing and hoping that my grey hair would grow in "pretty" (I had two aunts with beautiful white/grey hair), I finally realized I would not get so lucky and I just looked OLD.
So I've been coloring with Natural Instincts semi-permanent color; I use the color called Chocolate Crème. It does a great job on my dark brown hair, and the greys come out a little bit lighter, sort of a dark reddish brown color, that almost makes my hair look highlighted. So far I'm happy with it! The color is inexpensive and easy to do myself.
