What color do corpses look like to you?

I have noticed that when a necro does anything funny to a corpse, it looks dark or even black. Is this normal?

Someone in-game claims it should never look black?

Any thoughts?

any corpse that a necro has "used" in some fashion turns black, this just signifies that the corpse cannot be used again for the necromantic arts.

Thanks, so that goon who claimed it was a video card problem is just an absolute goon, spreading FUD.

BTW, I really dig messing up corpses...the bosses look really cool blackened with their aura still intact
