What base color for U.S. modern desert troops????

Ok, best match is Humbrol 121. 72 is too grey, Armour Sand is way to yellow.

Hmm... I've used Armor Sand too, but I'm looking at my unissued set of DCUs and the base color is almost pink, not yellow. I'm thinking maybe just a drop of red mixed in with the Armor Sand may do the trick. For the darker brown, I use Military Brown, and the other shade of beige I've had some success with RAF Middlestone, believe it or not.

I'm with HeavyArty on this one. Model Master "Armor Sand" is my pick for 3- and 6-color desert BDUs as well as WWII khaki items.

Testor's Model Master Enamel Sand is a straight out of the bottle match for either base color of three color (modern) or six color (Desert Storm era) desert camoflage uniform (DCUs).

i use humbrol 72 plus a lil white.
