This scheme is based largely around a colour plate I found online, but draws a little inspiration from 'The Last Samurai' too. It is quite involved, but it is intended for a small skirmish force, so I am willing to put in the effort.

Red Armour

1. Basecoat with Khorne Red.
2. Drybrush with Wazdakka Red.
3. Thin some 2:1 Khorne Red and Incubi Darkness and shade all recesses.
4. Mix Wazdakka Red and Ungor Flesh 1:1. Use this colour to add fine edge highlights to the plates.
5. Increase the amount of Ungor Flesh in the previous mix, so it is roughly 1:4 Wazdakka Red and Ungor Flesh. Now selectively highlight any corners or exposed edges.
6. Finish with :specular highlights of Kislev Flesh.

Black Stitching

1. Basecoat with Black.
2. Run the side of your brush over the stitching with some The Fang, just catching the edges. I would recommend doing this in and upward motion.
3. Mix The Fang with an equal amount of Blue Horror and selectively highlight the pars of the stiches that would most catch the light.
4. Finish with specular highlights of Blue Horror.

Blue-Grey Cloth

1. Basecoat with 1:1 Eshin Grey and Stegadon Scale Green.
2. Shade recesses with thin Abaddon Black.
3. Mix your base colour 1:1 with Mechanicus Standard Grey and further enhance the volumes with some fat highlights. The difference at this stage is subtle, but it is a great way to tidy up after the shading.
4. Apply chunky highlights of Mechanicus Standard Grey.
5. Highlight again, with Dawnstone coverring a smaller area.
6. Selectively highlight with Administratum Grey.
7. Pop specular highlights of Grey Seer where needed.

Black Cloth

1. Basecoat with Black.
2. Glaze and pick out the general shapes with 1:1 Black & Dryad Bark.
3. Take the previous colour and mix it 1:1 with Stormvermin Fur. Use this mix to apply some general highlights to raised details.
4. Mix the previous colour 1:1 with Rakarth Flesh and more selectively highlight.
5. With pure Rakarth Flesh, add small highlights within the previous stage.

For the laces on the sandals, I simply picked them out with :rakarth flesh, then selectively highligghted with Pallid Wych Flesh.

Cream Cloth

1. Basecoat with Screaming Skull.
2. Wash with Seraphim Sepia.
3. If any parts need extra shading, I would recommend additional shading by hand with 1:1 Tau Light Ochre and Dryad Bark.
4. Selectively highlight with 1:1 Screaming Skulland White.
5. Pick out very small White highlights to finish the cloth.

Skin

1. Basecoat with Kislev Flesh
2. Wash the skin with Reikland Fleshshade.
3. Highlight with Flayed One Flesh.
4. Add specular highlights of Pallid Wych Flesh on the tip of the nose and select areas.

Black Hair

1. Basecoat with Black.
2. Pick out hair strands with a 1:1 mix of Abaddon Black and Kantor Blue.
3. Mix some Kabalite Green into the previous mix and selectively highlight curved edges.
4. Now mix in some Fenrisian Grey and pick out an even smaller area.
5. Finally, use pure Fenrisian Grey to very selectively highlight curved edges where the light would hit.

Black Saya

1. Basecoat with Black.
2. Glaze a highlight of Dark Reaper on raised areas.
3. Apply fine highlights of Thunderhawk Blue.
4. Selectively higlight Fenrisian Grey.
5. Mix some White into your Fenrisian Grey and apply specular highlights on upward facing corners.

Katana Blade

1. Basecoat with Leadbelcher.
2. Wash with Nuln Oil, pulling pigment away from the tip.
3. Establish a highlight with Ironbreaker, and also edge highlight.
4. Add a small highlight of Silver RLM01 Metallic and eghe highlight more selectively.

Gold Details

1. Mix a little Silver RLM01 Metallic into Retributor Armour, until you see the colour desaturate to a point when you are happy. Now basecoat all gold details.
2. Wash/recess shade with Reikland Fleshshade, where needed.
3. Where you want to emphasize deep recesses or a define a change in material, use some Rhinox Hide and a very fine brush. We are aiming for a fine line here.
4. Increase the amount of Silver RLM01 Metallic in your Retributor Armour and highlight.
5. Finish with some specular highlights of Silver RLM01 Metallic.
