Paint question

I want to paint my Sturmovik in green/brown camo scheme. Like this...



Checking out a few sites earlier, it says AMT-1 is brown, but WEM say it's grey (2 types, AMT-1 light grey and AMT-1 dark grey). I read a review of the WEM paints on another site that says the 'grey' is more of a brown colour, but is it the same brown colour as pictured in the scheme above? Or is the colour above AII Light Brown or AII Dark brown???? It's all very confusing!

I don't know what the WEM is but it is wrong.According to my info AII was of many tonalities because it was not a part of the tonality number but it was a sign of a kind of semi-gloss paint for painting wooden and fabric covered surfaces from 1943 to 1944.The next part of the paint name was just the proper name of a paint. So :

AII Swietlo-koricznievyj ( FS595 - 20260 , light brown with sand tonality ) - Humbrol 118/Gunze H310/Testors 1732
AII Koricznievyj (FS595 - 20111 , dark brown) - Humbrol186/Testors 1701/Tamiya X-09

The same was with AMT paints.So AMT1 ( semi-gloss paint) or A-21M ( matt paint) Swietlo-koricznievyj (Light-brown with sand tonality) FS595 - 26306 or 36350 Humbrol 118 or Humbrol 83 for the second FS595 number/ Testors 1792/Tamiya XF-49

For the AII Zielonyj (green) FS595 - 24258 should be used Humbrol 114/Testors 1571/Tamiya XF-13 or AII Tiomno-zielonyj (dark green) FS595 - 24062 Humbrol 149/Testors 1764/Tamiya X-05

Thanks Wurger, I solved the problem by ordering all WEM's russian paint!

Although i already have the Humbrol greens.....

(WEM is White Ensign Models (UK online model shop) range of enamels, they're supposed to be very accurate)

THX Muller.Now I understand.
