I clicked the Tamiya chart, looked at Deck Tan, then went back and clicked the Model Color chart,,,,,it looks like 837 or 917 would be close
looking here,,,,,,I don't see a close color in the Air line, just the Model Color line,,,,,,,there are also the Game and Panzer lines to look through

I can't seem to get the Model Paint Database to load,,,,,,I think it has both the Vallejo and Tamiya ranges, which would give a one to one comparison
