It may be a stretch but, that looks like a tone I see where paints are sold for camo'ing firearm, etc.

Weird as, when I had to desert tan some sub gun mags I had, I actually tripped across the paint at a local ACE hardware (but, that was over 10 years ago)

When I need paint for camo projects now, I go to Brownells ( www.brownells.com ) IIRC

Sure hope this helps ya

Best o' success!
