Hi Weaverfish, and thank you! Sorry for the late response, I have not been that active as of late.
I spray paint them using corax white, and for the blue I use GW paints, and I start with thousand sons blue. I then apply a wash of coelia greenshade. Then I paint the raised surfaces with sotek green, and then highlight the blue with a layer of temple guard blue, finally baharroth blue.
For the dark blue scales I use kantor blue with a light highlight of alaitoc blue on the edges. For their hide on the front of the torso I use german camo orange ochre (vallejo) for the base. I then apply a wash of reikland fleshshade, then I paint the raised surfaces with tan yellow (vallejo) and finish with a soft highlight using bonewhite (game color). I reckon that any other ochre/beige paints will do.
