Moving on from where I left things in Part 2, you can see that I have finally achieved total surface coverage with my painting on these guys. All the armor, weapons and flesh was covered, tether liberally, with Black Templar Contrast paint.

| Red ones go faster yes? | 
I had to go back and paint 
Corax White on the red areas that accidentally got black paint on them   before repainting 
Baal Red back onto the armor. I was really sloppy with the 
Black Templar paint so this was a bit of a process, but the models already look better for it.  A few of these models have skulls, and 
Skeleton Horde was painted on them. The model with the most skulls is the standard bearer who has a whole collection of them dangling from his banner. Speaking of which, the banner has a classic evil sun totem which I used 
Blood Angel Red Contrast Paint on.

From here on out, I decided to focus on the leader of the pack, who is an older miniature from the '90s and was sculpted by a different sculpter than the other guys. I think these differences help him stand out from the others and I think I like that a lot. If you got this model when it first came all, he was leading a rabble of black orcs who were all in the same pose, making it a little more challenging to pick him out of the mob.

On top of the Black Templar Contrast Paint I added a layer of Caliban Green.

Next I added 
Snot Green. The 
last time I painted a black orc I used 
Bilious Green at this step but I found it to be too intense, and I really had to work at bringing it back down to a darker tone. 
Snot Green, although intense, is a darker color so I hope this will be easier to work with.

You got to admit, he just screams "90s red era at this point doesn't he? I really like the way the red just pops visually, so I reinforced that with an edge highlight of Evil Suns Scarlet.

| Nuln oil wash.

A wash of Nuln Oil took the edge off of the flesh, and I think I am good with this at this point. I was impressed with the way the Black Templar low/highlighted the axes, so in an effort to preserve that effect I used my trusty old Aleenes Gleams Pewter to basically trace over the natural highlights caused by the Black Templar paint. I think this met my expectation rather nicely. The metal of the chain mail was painted also using Pewter but with a coat of Nuln Oil Gloss applied over that. 
And we are at the finale now:  the most important part here, subtle though it is, was adding Agrax Earthshade to the recesses of the red armor. This gave it a bit of depth and grit that the armor seems to be lacking otherwise.

| Finished. | 
I used some thinned 
Hobgrot Flesh on his knuckles and prominent facial features  for a final highlight of the flesh. I think I like how that turned out. Next I added a few vertical lines of Hobgrot Flesh to his big bottom lip. Then I applied two coats of 
Carroburg Crimson on that lip. And I think that's turned out alright.

| 3/4 shot. | 
I edge highlighted the two axes with 
Stormhost Silver. This really gave these weapons a gleaming vibe I like. Normally I try to make my orc (and ork) weapons a bit more browned, rusty and used looking, but these guys are coming straight oughta Zufbar and I imagine that their diminutive hosts hook them with some finer kit than their Badlands brethren. Never-the-less I wanted to rough up their armor a bit, so 
Stormhost Silver was used (randomly) on the armor edges

And that's prety much it really. Next week I  will be applying these same techniques to the remaining Black Orc mob.
