Does anyone know of a hair coloring product that offers grey as one of the colors?

Wierd desire!!! I've got ALOT of premature grey hair, and rather than trying to keep it covered up, I want to find a shade of grey to blend it. There used to be several nice ones on the market, but I can't find any.|||Nice 'n Easy from Clairol has a selection of grey colors. Check out the local Wal Mart hair color section and see what you can find. There may be other brands as well.|||i just have 1 question?? why would you want to die ur hair Grey??????|||Grey/silver is beautiful. Go for it. There was a clerk at a Von's store with it all grey/silver. I know she was too young, but it looked great! It's as good a color option as any.
