Good evening, Dan!
About the colors of the horses:
- generally I use black acrylic primer - at present Mr.Finishing Surface 1500 Black of Mr.Hobby
- for the colors I use Vallejo acrylic paints pure or mixed of the following components:
Panzer Aces 302 Dark Rust
Model Color 131 Orange Brown
Model Color 140 Flat Brown
Model Color 148 Burnt Umber
Sometimes I lighten the color using Model Color 021 (Medium Fleshtone) or make it darker with Model Color 169 (Black).
I find very useful to add a few drops of AMMO MIG-2000 Acrylic Thinner when I mix the colors - it makes the mix more smooth and retard the curing.
Take care-
Sandor
