I like both the Silver and the Gold. I have a Gold AW and S2, and ordered a Silver S3C.
As far as the S3 Gold is concerned, I'd have to compare it in person in a well lit Apple Store (ha!) to judge the color.
Right now I'm operating under the assumption that it's an optical illusion when combined with the color of the band further supported by the name of the band- Pink Sand. (I think that's the name of a Go-Go's cover band.) I think it's just the proximity of the band's color and maybe it's name that makes the gold look pink.
But I haven't seen it in person with a control, so I'm withholding judgement.
