Here is how I paint the unifying weapon colour on my Deathwatch veterans for Kill Team.
- Basecoat the area with Khorne Red and Abaddon Black, mixed 1:1.
- Edge highlight everything with a chunky line of Khorne Red.
- Add a fine highlight of Wazdakka Red to all of the same edges.
- Highlight corners and exposed edges with Squig Orange brushing towards the centre.
- Pop specular highlights of Lugganath Orange in the centre of these highlights and on corners.
