According to the Standard Catalog of American Light-Duty Trucks, "while early production trucks originally had a Tucson tan finish, Argent silver later replaced Tucson tan and the later trucks also had Argent silver finished grill bars with red stripes."

For 1949 "...elimination of the red stripe on the Argent silver grill bars were the two most noticeable styling changes for 1949."

For 1950, "The grill recess was finished in an ivory color."

I personally like the either the tan or ivory, especially if you're using the optional stainless grill bar trim set. I think the lighter colors make the grill stand out more. I painted the recess panel on my '49 a beige color that matched the original paint on the '48 grill I used.
