Does anyone know if OEM leather interior color code 642 (light beige for 1993 Bonneville) is the same as OEM code 672 "oak" for 1998?

The colors look identical in photographs but I want to make sure before I buy new seat skins off of eBay - want to make sure I'm getting the same color obviously. I know GM was famous for changing codes for identical colors over the years.

Thanks to all who respond...

In 96-99 there were two colors. one was a lighter tan than the other. I dunno what color the common light tan was, but the other I thought was called camel. Camel is the one that matched 92-95.
