This recipe is mainly here as a reminder to myself; it uses several paint ranges to achieve an effect I'm sure you can manage more simply! I chose the red-orange desert scheme to complement the warm green tones of Salamanders Space Marines.
Update: I've since moved to a slightly less lurid colour scheme for these bases, as they can end up overwhelming the model! You can find it here in my Salamanders tutorial: https://paintpad.app/recipes/2325-salamanders-v0-9
