I have a 12D 68 LOS car and it was gray/white, I read in one of my books it was gray white to early mid year production for 68 then changed over black/aqua. To late right now to dig through my books but I'll look and post what book it's in. I know you can't believe everything you read but I know what my car had. GM also still sells the paint and it was a pretty good match, also dries pretty hard unlike the repop stuff. Not water proof, but water resistant.
