I gave up on these guys back at the end of Monster May(hem). I couldn't get Hastur painted right, so I didn't see the point of having a go at his merry band of followers. But then I decided to try something different...
Here's the secret weapon: Citadel contrast paints. I picked these up last week while buying a new pot of Serpahim Sepia to finish my Warhammer chariot. I've never used contrast paint before but I have watched a few tutorial videos on them and they look
straightforward to use (famous last words).
I've read that contrast paints need to go over a smooth, even primer, so the cultists were stripped back to bare plastic and resprayed with white primer. I painted their skin, Tommy guns and shoes before tackling the yellow; as contrast paints are transparent, any specks of black or brown would show through.
I bought Nazdreg and Iyanden yellows to give me a choice, and I decided to use Nazdreg as it's a bit darker. I don't know if I'm supposed to thin the paint, so I just picked up a size 3 brush, dipped it in the pot, took a deep breath and got to painting.
