The color out of a rattle can will match, but the quality won't. I've painted that way and it's rough. Nothing beats misting on with a quality gun.
Dan, I would start at an auto paint store. They can color match it. The problem is, some places require a full pint for customs. That can get pricey. But once you have the color you can strip the fork, prime the fork, then give it to any auto body place to shoot. I'm sure for just a fork that won't charge you much.
