Chad - they were basecoated with coal black, so they have a bluish tint compared to the rock. I don't want them to distract from Krell, which is why I kept them muted. In fact I'm thinking of removing the skull from the base.
Elly brought up a good point recently - the axe blade. I'm no expert at black, and the fluff really insists that the axe is black. It's called the Black Axe of Krell for a reason.
Now there are a few ways to approach this, each harder than the last.
A. Use nice oils to get some rust/corrosion effects. Quick and dirty. Problem is orientation. Armor is worn one way, so corrosion runs with gravity. How do you deal with something that moves around a lot?
B. Not very time correct, but some modern black blades are actually painted/powdercoated/whatevered black, and the blade edge is still naked metal. That'd break up the black, though the little corrosion circles would present a problem.
C. Make the blade of some other black substrance, i.e. onyx or obsidian. I had originally suggested this, but if it's an effect that even Elly struggles to get right, what chance do I have?
A is obviously the easy way out, and B is doable. C is probably not, but could be worth a shot.
Ideas fellow painters?
