It's not blue, but that hint-of-green silver that was a special-order original color and just came up on a CSX for sale is just a deadly shade for these cars. Champagne Mist, I think it's called. Foofy name, but more ssssssnaaaake colored than anything else I've ever seen.

EDIT: CSX 4199. It's on Cobra Country.
