Bamagirl, I would advise using one of the Loreal products, the Excellance or Prefferance are my favorites. You should never go more than two shades from your color now without professional help. If you try to stray too far from what it is now, you might end up with a diaster! What I would do is pick the color that most closely matches your hair now and go two shades down from that. I don't ever remember seeing a picture of you so its kinda of hard to give color advice without knowing what you look like!! Anything with ash in the title has the potential to be grayish or greenish so I would stay clear.
