47-55.1 AD '47-'53 Grill bar ORIGINAL PAINT color options?

[89AKurt]

Q: Building a '48 (1/25 scale Canopy Express), want to paint the back part of the grill bars an ORIGINAL color. I owned a '48 1/2 ton years ago, it's was light green. I've seen white. I assume black was an option. Did color denote trim grade, or weight (for example)? Not interested in your opinion that a hot rod restoration could be whatever color you're painting it do whatever you want, that's completely different and seen several threads stating that opinion, but none about the correct ORIGINAL colors available. Thank you.
