@ Rizhail To get the effect you are looking for, the closest you can get while still being easy enough to make the army look good and not take months is similar to Cheese's suggestion. Go lead belcher, drybrush runefang(or any other bright silver) and use the Ankhelion Green(even though its totally blue with a slight hint of green, weird misleading name for no reason).

What you could do to make the effect even better is do the above then hit it with another drybrush of the bright silver and do a thinned down version of the Ankhelion green over it again.
