Welcome, MoparMcK

I don’t know in the specific case of a 1969 Newport like yours. Fwiw, I had the same question wrt a 1972 GY8 NYB with H7Y5 interior, and it turned out to be ivy gold. So, my bet would be ivy gold based on that first hand memory and also on my recollection of earlier posts, see the following search:

Search results for query: Ivy gold

My recommendation, though? Ask for manufacturer samples of each type and compare with unfaded spots in your carpet. You should have some such spots under the front bench seats, or under the back bench.

PS: please post what you find?

Thanks. I actually just ordered the ivy gold. It seemed to be a better match to the seats than the gold. Also my carpet was so wore out and dirty. There was not a good color sample on it. Either way it will be better than the bare floor.
