'Nid Scheme

[Virtual Falcon]

Hi,
I am still thinking about my 'nid scheme and found this picture on GW contest for the tyranid warrior:
uk.games-workshop.com/tyranids/contest/images/t8.jpg
What I want to know is any ideas on how to paint the carapace in that picture, as it is the sort of thing I've been looking for.
My idea fir the scheme is leviathan skin colour(Bleached Bone, then BB and Skull White) but then add watered down ice blue/any really bright blue(as in almost cyan). Does anyone know how this might look?
Thanks

For the contest piccy i suggest using a regal blue all over then for the edges enchanted blue then a 2:1 mix of enchanted to fortress grey. for the ridges get a very fine detail brush and go into the ridges in ice blue.

Thanks!
This is just a general question but, instead of regal blue could I use enchanted blue w/small bit of chaos black? and would that work for most colours?Because of some parts where you need blood red, scab red, red gore etc. it would be a lot heaper than buying all those paints which I might never use...

Nah... I usually find chaos black to overwhelming. Ruins your stuff quite easily
