With a LOT of people blue just doesn't work and some grays/silvers don't work. I figured it was going to be dark blue closer to your roots and fade down to a lighter blue. It does look good even if it's not what you wanted. That's probably why I do my hair at home, I'm not picky, but I want it a certain way if I'm going to pay for product AND time.
Blue's always held well in my hair, thank goodness. Just doesn't seem the silver will. We tried manic panic in the oldest's hair and it looks awesome (she wanted red), and the youngest wants green, so I'm thinking of looking to see if they have a silver, or a blue-ish silver, and if they do... I might give it one last attempt myself.
