Some ESB Yellow questions

I think I've decided to do all my damage topically for my fett, but before I go that route I had a few questions about the yellow damage on the chest/collar plate. Is reefer yellow the color used underneath or is it something like yellow zinc chromate? I can always do layered with a generic yellow spray, but I was curious to see what was closest.

Thanks,

me and ponte were discussing this like two nights ago....some people say zinc chromate which it kinda looks like...but in his opinion that doesnt make sense they had UP Armor yellow there for the shoulders why bother with another yellow? So its debatable, try some color swatches
