As promised, here is a quick and dirty tutorial for how I paint camo pattern for my Airborne Imperial Guard army. You can read about it more in depth at
Pensacola Warhammer
I start by airbrushing the miniature with Vallejo Surface Primer Grey. The light, neutral color will help keep the other colors from dulling too much and making the miniature hard to see.
I base coat all cloth material and anything that I want to be camouflaged with Vallejo Stone Grey. Now for applying the actual camo pattern
The secret to achieve a "digital" camo pattern on an infantry miniature. The size and over all surface available on an infantry model makes it almost impossible to get an actual digital camo pattern. Instead, you have to give the impression or illusion that there is a digital pattern there.
The first color is the green. I used Vallejo Model Color Russian Uniform WWII. I dip a piece of foam into the paint. Before I touch the model with the foam, I dab some excess paint off on a piece of paper or towel. I then gently dab the model with the foam. You don't want to go over board because you'll be putting on another color, and you'll want the other two colors to still be visible.
Repeat the process as above, but this time with a brown color. For this, I used Vallejo Model Color Saddle Brown.
The final step is to go over the model with a black wash. This does a couple of things. Obviously, it brings out the details that the camo might be hiding, but it also helps to blend the three colors together so there is not a stark difference between grey, green, and brown.
Next time I'll show how I do the armor and gun, so stay tuned.
