Does the carpet match the...

Looking at fender tags and interior codes, it looks to me like carpet usually matches seat color, yes?

So then I was wondering how many different interior areas could be ordered in different colors. The exterior paint is one, the seat upholstery is another, and the tags talk about the interior door jamb area - seems like it would be color matched to the interior rather than the outside paint. And I have seen several cars with red interior and white headliner. What about the dash?

So that makes:

exterior paint color
exterior trim color (64 GT stripe)
door jambs etc
dashboard
carpet
seats
headliner
door skins

Now I doubt all of those could be colored differently, which ones were grouped together for color purposes? I'm thinking of early A's especially.
