The recipe for painting Sisters Repentia for my army.
  Priming and Base Coats
- Prime using   Corax White  
 - Paint robes using   Akhelian Green  
 - Paint skin using either   Guilliman Flesh  or   Darkoath Flesh . Add additional layers until desired skin tone is reached.
 - Paint leather using   Snakebite Leather .
 
Detailing
- Paint eviscerators and shoes using   Black Templar . Use   Sycorax Bronze  for the hilts.
 - Pick out silver details using   Iron Hands Steel .
 - Pick out gold details using   Retributor Armour .
 - Use   Leadbelcher  for the blades of the eviscerators, power armor implants, and any other metal that you want to have darker than the rest.
 - Paint purity seals using   Blood Angels Red  for the seals and   Gryph-charger Grey  for the parchment.
 - Use color of your choice on the stones that are part of the model's base. I used   Basilicanum Grey .
 
Shading
- Shade everything that isn't contrast with   Nuln Oil .
