I've always liked the idea of Imperial Fists as a legion except for the unfortunate fact that they are yellow. Yellow and I don't get on, it has a habit of going green at the merest hint of brush contamination and even when it works it's either so dull as to be anonymous or so effervescent it dominates the pallet.
So here was a chance, not shading, no highlights just slap it on is what GW said. The result is below.
The yellows and browns are Contrast paints, the metals and red traditional acrylics and washes.
I'll have more thoughts on Contrast in a later post.
