Iridescent Nids? Would like some help.

[soldierz]

Hey guys, trying to paint my Nid's carapaces in some sort of iridescent paint or style (Like the picture below). Always been a fan of beetles and the way their shell's give off that beautiful look, I just need help to make that dream come true so that I can smile and admire my work as I eat space marines. Any tips or ideas are welcomed.

This may not be what your expecting or achievable but... A friend of mine used to work in a car body shop. Apparently he sprayed up his whole Necron army with pearlesent White / purple bodyshop paint. Hmmm?

There are pearlescent additives you can buy which will turn any paint into a metallic.

Possibly a deep metallic purple highlighted with metallic green would work if you can't find an actual changes-shade-based-on-the-angle pearlescent paint.

Basecoat it with silver and/or gold... then use the "inks" or "ghost tints" depending on the manufacturer. Airbrush them on in thin layers and then go back over it with some gloss varnish.

should do the trick quite nicely
