Questions related to Broadcast Sheet and Fender Tag coding

Thank you for the reply.

HL4 (or I guess L4) is a bit vexating for me. I have seen it referred to Summer Sand, Desert Sand, Parchment, Beige. Looking for something definitive. I get Plymouth, Chrysler, and Dodge had different names for the same color. I came across a 1972 Chrysler Passenger Care Color Reference Chart. Under the Monaco, Polara, Coronet, Charger column, it refers to L4 as Parchment, so that's what I am going with.
You are correct. L4 was called Saraha Beige at Chrysler and Parchment at Dodge per the brochures:

I think in 1973 it became Summer Sand at Dodge.
