For my Arizona Iced Tau Army

Prime

1. Prime with Leadbelcher

Undersuit

1. Base Coat Corvus Black on the undersuit (Avoid areas not black, check reference image)
2. Edge highlight with Eshin Grey
3. Fix areas that were accidentally covered with Leadbelcher

Highlight (Contrast will still show it)

1. Edge Highlight armor panels with Stormhost Silver

Armor Panels

1. Make a light layer with Aeldari Emerald on armor panels
2. Make a light layer with Aethermatic Blue on armor panels
3. Base Coat Retributor Armour on the Tau emblem
4. Base Coat Runelord Brass on the hoof panels

Tiny Details

1. For lenses, get a very small drop of White Scar on the lens, let dry, then water down Doomfire Magenta to put on top
2. Paint accent metal pieces with Leadbelcher
3. Use contrasts like Frostheart or Asurmen Blue to color communications devices

Shading

1. Shade Coelia Greenshade on armor panels
2. Shade Reikland Fleshshade on the Tau emblem and hoof panels

Cloaking Effect

1. Use Agrellan Badland and Agrellan Earth to make the base texture, and use it on some of the model for the parts that are already cloaked
2. Cover the transition between texture and the uncloaked suit with Abaddon Black
3. Make a strong, thin, jagged Corax White line parallel to the black transition, on the side of the already-cloaked part
4. Make a thin line of Thousand Sons Blue on the cloaked side AND uncloaked side (you should have in order: UNCLOAKED, BLUE, BLACK, WHITE, BLUE)
5. Stipple in order, on both sides outward from this transition Ahriman Blue , Temple Guard Blue , Baharroth Blue
6. Add extra disjointed stippling of Baharroth Blue slightly outside the transition area

Varnish

1. Varnish with Satin spray
