"Whilst an Ork will belong to a tribe, they also belong to a Clan.....
An Ork tribe usually contains Orks from many different clans, so when tribes fight each other Orks will often find themselves in combat with foes from the same clan. This is considered normal, as an individual Ork's allegiance is to his Warboss rather than his clan.
six large and truly significant clans:
Bad Moons: The richest Ork clan, due to their teef growing quicker. The Bad Moons are the closest thing Orks have to a merchant class.
Blood Axes: Distrusted by other clans, the Blood Axes make use of "un-orky" tactics such as camouflage and even battle plans.
Deathskulls: Famed looters and scavengers.
Evil Sunz: Epitomising the Orkish love of vehicles that go fast and make a lot of noise, the Evil Sunz have a high proportion of Speed Freeks.
Goffs: Close combat specialists.
Snakebites: Staunch traditionalists, who distrust many forms of technology. "
In light of this, would it be fluff-friendly to have an
army (tribe) that has its units painted according to different
clan schemes?
Whenever i see "professional" ork army photoes they all seem to be painted according to the same Clan scheme regardless of the unit rules wise.
what's the general approach to Ork painting?
