Need some advice on zombieskin

Are about to start to paint my awsome undead warband and have all the colorshemes in my head but i want my zombies to be more like blue/grey skin tone.
but have no clue on how to achieve that.

the only certain thing i know is that i will prime them skull-white.

<- something like that. (snatched from google.)

Hm, there was a thread on here which had a female of that skin colour... I just can't remember where (somewhere in the gallery).

The recipe for the skin colour was the following:
1. Basecoat Pale Flesh/Vallejo Pale Blue
2. Shade by adding purple ink to the mix
3. Highlight by adding white

Here's the picture (hopefully, someone will recognize it and point out the original thread):

oh thanks thats awsome.
whats the equalent of those colors if you choose GW?

The picture is from Ziggy Star-dust's Undead Gang in our gallery.I agree with what Elizar wrote about the paint scheme. In GW colors I would say start with Shadow Grey as your base blue.
I recently had some success with blue skin, but I went about it in a weird way. I used blue, grey and green paints to build my layers. The green is used sparingly as a way to emphasize the blue tint of the skin and purple veins. I would post a picture, but I'm not quite finished yet.

I think pale flesh, purple ink and skull white are GW colours.

As I didn't have pale flesh myself, I just mixed Space Wolves Grey and Elf Flesh and it turned out alright so far. If I get some work done on the miniature this week (I hope I get started with painting after my holidays again soon!), I can take a picture to show you.

Oh, and thanks for the link, UnderBheit

Thanks for the tips guys!
that with elf flash and spacewolf grey shall i try tomorrow just sprayed my guys and totally messed up with one of my zombies so need to make a new one.
