Black Templar is a Citadel Contrast paint that provides a quick and efficient way to shade black armor or metallic surface
Contrast paints are designed to simplify shading and highlighting
For edge highlights on Black Templar armor, consider using Russ Grey thinned with a touch of water to achieve a smooth flow
 You can also use thinned Black Templar to shade metallic colors like silver 
 Mix it with Contrast Medium for better control
 Apply Black Templar directly over a light-colored primer (such as Grey Seer) to achieve a dark, blackened effect
