+1. Damn, but those look nice. I've always been on the fence about Imperial Blue, as pictures of it always seem to have a green tint to it, at least to my eyes. But I like these...
I think the key is using it with or near a green shade, which sorta overpowers and blows away the 'green' tint of the blue. I'd suspect the same is true when using saturn yellow (also green tint) - if used with/near a green chip, it will appear more yellow with no green overtures.
