colors for a japanese type 97 tank

I would like any help on colors for the Japanese medium tank type 97 Chi-Ha.I’m building the Tamiya model of this tank and it’s not to clear on the colors.It gives the color call out as khaki,dark red brown and dark green.I have at least 4 different shades of khaki and who knows how many dark greens. [8-)] I know i don’t have any marked dark red brown. [*-)] Been a WIP on and off for about 2-3 years (mostly off [whstl] )and would like to finely finish it.Any help would be appreciated. [:D]

Basicly a redish brown, a SLIGHTLY brownish yellow, and a dark green. I wouldnt worry to much about being EXACT with the color scheme. I doubt anyone will call you out saying YOUR GREEN ISN’T 0 64 0 its 0 57 0. As long as it’s close I wouldnt worry
