I thought, some months ago, that I came across a Hinderer with a "ghost" scale. Could've been a special order or a customized version, but it was a whitish translucent scale and just looked awesome. I haven't been able to find it since. Just going off Hinderer's basic options, though, I'll go with the bronze anodized titanium and all stonewashed.
Are you sure it was white? There is a pale, translucent green one, which may be the one that you have seen.
