I'm gonna take a chance that someone can help me out: I'm looking for the proper color to paint my German WWII fire engine....the original specifications call for "dunkelgrun, glazend, Farbton 30". I know that reads "dark green, gloss, color shade 30" , and the RAL reference code is given as RAL 840 B 2. Any ideas on a commercially available paint that would match or closely resemble this shade?.
