I've bee slowly working on the genestealer cult from the deathwatch box. My goal is to have a simple paint scheme, but my lack of free time has made this a longer than hoped progress. The purestrains, primarch and familiars are basically done now, and the hybrids have the base coats.
For the purestrains blue and purples I have been using reaper paints, and I really like how bright the colours are on them. For the hybrids I need to do some washes and finish up the lights before moving onto the cultists and characters.
