Field Medic Vigilant
This is a test paint to see if I like the look of things and I'm pretty happy. I unfortunately didn't have the bases with me and it was a terrible experience trying to paint the model.
I used Lead Belcher for the armor pieces, Black Templar for the uniform, Abadon Black for the leather, Valejo Pale Sand for the face base and scroll, Game Color Off White for the medical case, Snake Bite Leather for brown, Ork Flesh for green, Reikland Fleshshade for the face, and finally some Nuln Oil on everything but the face.
The blue paint is fluorescent blue to create a glowing effect when hit with a black light. The emblem paint will also serve to differentiate the Exaction (blue), Subductor (orange), and Vigilant (red) squads.
