vietnam colors??

If my eyes (and screen) aren't deceiving me, I'd say that your basic shade OG 107 is what you got on them right now..  The body armor color's right too, although you may want to stain/fade them a bit here & there... Although you might wanna work on those seams a bit more..

Aircrew boots are all black, but a number of them wore jungle boots anyway...

Here's yer basic Jungle Boot... These are newer issue, circa 1990s, but that don't matter in 1/35th scale..

Here's another attempt at getting the pictures up.

Those figures are wearing OG 107 jungle fatigues (see Stik's above) rather than Sage Green flightsuits...  The flight helmets would be Olive Drab overall, but since they're a personal item in a combat zone, you'll see a lot of custom ones, so anthing goes, almost.. Here's a few examples..

Mine, an SPH-5B:

First, check the white balance on your camera. It lookslike you're have a daylight setting under incandescent bulbs.

Second, in Photobucket, three are 4 boxes that appear when you scroll over your thumbnail image. Copy  the text from the bottom one labeled "IMG Code" to post here. The pictures you've posted are too small to provide any real feedback.

A couple figures I've been working on looking for any tips for the uniforms.  The photos came out just a little darker in photos than in person.  Haven't really done much with the skin except get a little color to start with.

Jungle fatigues start off in a nice dark olive green color, shade OG-107 officially. They faded quickly with wash and wear. I had sets that varied from a tanish green (similar to RLM02 or Slate), blueish green (similar to SAC green), or grayish green (RAF cockpit green).

Here is a lighly faded set.
