Yeah, I think most people get confused with the “Khaki as a Color” issue especially for WW2-era uniforms. Khaki was actually the name for the material, a khaki-cotton twill that was actually a “mud” color…
The Army called this “Khaki”, even though it was the standard-issue OD shirt for enlisted…

And this was the Officer’s Khaki shirt-color, which is more a “Chocolate Brown”. The actual uniform called “Pinks & Greens” consisted of the tan shirt & tie and trousers with the dark green jacket… The tan color DID have a pinkish hue to it in sunlight, hence the name…
The shirt below is probably the closest match to Tamiya’s Khaki Drab XF-51…

I know this is beyond the scope of the original question, but I was bored, just watching some paint dry…
So, to summarize the “Khaki Question”…
WWII U.S. military uniforms and gear were NOT khaki.
There was but one uniform used in WWII that was khaki- the summer service uniform… No other uniforms or field gear, not M41 field jackets, tanker jackets, cartridge belts, haversacks, wool shirts or trousers, musette bags- not even the mighty M1942 paratrooper jump uniforms were khaki. NONE OF THEM… They were “OD”, short for “Olive Drab”. This is indisputable historical fact, documented and easily demonstrated. The quartermaster corps, the War Department, the Army, the Air Corps, and even the soliders refer this stuff as “OD” in official correspondence, supply catalogs, manufacturing specifications as well as first person accounts of the War…
