They don't. Inverness Green and Pelham Blue are both metallic though, so they could look like Fender LP blue. That turns green a lot, like the Pelham Blue, and when it goes green you are hard pressed to see it as something that started blue. Calling it seafoam is not accurate, but calling it "aqua" would be better.
Fender seafoam is a regular opaque color, and I don't think Gibson ever offered anything like it. The closest they got was the Kalamazoo baby blue, which is not green at all. But if you top-coated it with a tinted yellow it would get seafoam-y pretty quick.
Very Fender-ish, I know, but the custom color stuff really is their baby.
