Oh check this out....
So I simply take Model Master RAF Sand color and mix a bit of RLM 62 Grun. I look at it and think, "Damn, that looks to be the right color." But I wasn't sure so I researched it and Wurger and I came up with the same colors of SAC Bomber Tan, white, and a slight touch of Chromate green. I follow the mix of 20 parts Bomber Tan, 11 parts white, and roughly 0.9 part Chromate Green. I add a but more white to lighten it up and compare it to what many consider it to be the correct color.
Guess what?
It looks to be the exact same color as the sand/Grun mix that took me only 30 seconds to mix while the bomber tan/white/chromate green mix took me 20 minutes counting drops with three droppers...lol.
figures.
