I. Hate. White.
I really, truly hate painting things white. I tried painting my Deathwing dudes mre of a bone color (leftmost below- base color is Citadel Ushabti Bone, with a light coat of VMC Off White), but it just didn't look right. Then I tried straight Off White and Ivory (middle two- both from Vallejo) and settled on the Ivory as the 'least worst'. It's still a pain to cover up after the washes, though- so I'm thinking that after the sepia wash on the last guy dries, I'll try doing a thinned bone layer just to cover the spots where the wash was unruly, and then a couple Ivory layers.
But really- white sucks.
