It Won't Attract the Worm
I finished up the Trygons this week. After painting the bone on these guys I think I'm going to head back to it on the Lictors and the Warrior's Boneswords and try it on them as well.
For the bone I ended up doing some feathering with two colors at the base where it meets the pink attachy bits and then blending up to white towards the edges.
Up next I think I'm going to work on building more of the bigger stuff and finishing up the Carnifex, Zoanthropes, Biovores and Hive Tyrants.
