This recipe uses an airbrush for the initial stages, and normal brushes for subsequent refinement. The airbrush is absolutely not necessary, but makes the early stages quicker! I also rushed the process when making the photos; I'm sure yours will look better! Update: I've since decided this approach is a bit to vivid for a whole army, so a more muted, less neon method is included in my Salamanders tutorial: https://paintpad.app/recipes/2325-salamanders-v0-9

1. Prime the model with a cool neutral colour; I used German Panzer Grey . This model is going to end up with cool shadows and warm highlights, so a cool basetone will help.
2. Basecoat the whole mini with Heavy Black Green
3. From about a 45 degree angle, spray Warpstone Glow on the model for a first highlight
4. Add a highlight from above with Liquitex Vivid Lime Green Ink (use Moot Green or Livery Green if you don't have this ink.
5. Spray Night Blue from below to add shadows and build contrast.
6. With a regular brush, add highlights with Warpstone Glow . As well as the edge highlight, you can glaze Warpstone Glow to emphasise the volumes of the model
7. Add a second highlight with Moot Green , covering less area than before and only edge highlighting the more upwards facing areas.
8. Add a third highlight with Livery Green , adding some final glazes to the volumes of the model, and edge highlighting the most prominent areas.
9. Add final small highlights of Yellow Green (70.954) to where edges meet.
10. Using thinned-down Night Blue shade the recesses of the model. You can also glaze over transitions to smooth them if you like.
