Vergilius - regarding the whites, I painted them in oils. For his tunic, I used my normal white mix of White and Black (both W&N) + Old Holland Ochre (Old Holland) and I added some Italian Earth (Old Holland) to warm it up. For the shield, I wanted a cooler white. I dont remember exactly what I used (I should write these things down!) but I know I used Paynes Gray and maybe some Raw Umber (?).
