Anyone have a recipe for painting Servitors' skin?

[Nicodemus Doloroso]

As the threat title says, I'm wondering if anyone has a good recipe for that Borg-like pasty, greyish skin you see on servitors, like this:

I've got a few servitor-type creatures to paint up but not sure which colours to use -- I prefer the new Citadel range if possible. Thanks.

I like using a 1:1 mix of shadow grey and graveyard earth, highlighted with 1:1 of the basecoat and kommando khaki, pure kommando khaki then bleached bone on the highest points. It creates a greyish mottled skin that I use on my death guard. It would look good on servitors too.

 

I don't know the equivalents for the new range but shadow grey is a dark bluish grey, graveyard earth is a medium brown, kommando khaki is a light brown, and bleached bone is bone.

 

Hope that helps.

I go for a sicky/pale skin tone:

1. Basecoat black
2. Layer Dawnstone
3. Layer Pallid Flesh
4. Highlight Ushanti Bone
5. Wash Nuln Oil

(5) can be changed for the wash of your choice.  I use Nuln Oil to give all of my Mechanicus models an oily, dirty look.
