I've aimed for a Samurai feel with these Japanese Corporate troopers from Ground Zero Games.
Vallejo beastly brown was used for the armour, Vallejo charred brown for the trousers and upper sleeves. I overpainted some parts of the armour with GW red gore. Painting it over the brown has kept it fairly restrained, unlike the bright red you'd get from painting it over a white undercoat.
The whole figure received a wash of Vallejo sepia ink. The darker brown areas received a further wash of Vallejo black ink to ensure a good contrast with the lighter brown armour.
Weapons are Vallejo matt black with a Humbrol 32 dark grey drybrush. Flesh is Vallejo dwarf flesh with a sepia wash, highlighted with dwarf flesh and then with elf flesh. I'm not sure that it's an entirely convincing Japanese skin tone, but there's so little flesh on show that it hardly matters!
The officer's sword has GW red gore and Vallego bonewhite stripes.
A nice set of figures. 5 are armed with compact assault rifles, one a tribarrel support weapon and one a 6-round mini-missile launcher. The officer has an assult rifel and a sword (perhaps a katana?).
