Actually, I would call that color Fawn. It's a gold/silver mix. GM used it a lot on interiors. The Dash Pad would also have been Fawn vinyl, but they age to a darker charcoal grey color.
As to why Chevrolet chose that color for that interior, IDK? Perhaps they just had a Fawn column ready, and put that in, rather than waiting for an Automatic Shift Column to come back from the paint shop in Red. Just guessing.
