I know, it's an Oldsmobile site, but I don't belong to any Chevy sites (that's a lie, I belong to the Chevy Equinox Forum, but I doubt anyone there could help me out with this) and it might be a question that pertains to Oldsmobiles as well.

Looking at this document:

Can anyone tell me what the "WMH" stands for in the Body Side Stripe Color code?

Thanks,
