A good paint shop should have no problem matching the silver. I had the front of my car repainted and it matches perfectly, without any blending. I think its hard to match any metallic, but like i said, a good shop should be able to tint it to match just right.
When they did my car, they had about 6 different Silvers with the silver frost paint code. Each one was slightly different so they could find the perfect match.
