I used Contrast on both of the Primarch models I have
Ffor Curze it's his base. Specifically it's Skeleton Horde over a pre-shaded base, then drybrushed with Karak Stone.
For Sanguinius it's the daemon. I did Black Templar over Khorne red, then drybrushed with Mephiston Red.
I'm currently thinking I'm gonna use Basilicanum Grey over the same metallics I used on Curze (Iron Warriors > Nuln Oil Gloss > Leadbelcher Drybrush > Ironbreaker layer highlight > Stormhost Silver) to get the Metallic Dark Grey armour the GC-Era Wolves had for Russ when I get him.
