White Armour: The white armour is the most difficult part of this paint scheme. The main issue is that any errors while painting the black areas are difficult to correct and white typically takes multiple coats to get an even layer of colour on the model. I prime black, this may not be the most effective technique but I do it so that there is less black lining to do afterwards. I paint each section of the armour carefully during the base coat phase to remove the need for black lining later. Each section of armour is first base coated with Citadel, Ushabti Bone. I use the air version so that the paint is already thinned and can be used straight from the bottle. This takes 2-3 coats to get an even base coat, take your time on this stage as it will save time later on. The coat needs to be even and cover all of the black undercoat. Next we start to build highlights, I mix Ushabti Bone and Citadel, Ulthuan Grey in a 2:1 mix and apply the first highlight covering 70% of the surface area. Next I create a mix using 1:1 Ushabti and Ulthuan and cover 50% of the surface, next a mix of 1:2 Ushabti and Ulthuan to cover 25% of the surface. Finally pure Ulthuan Grey is used for edge highlighting and the extreme highlights on the front and top of the model. Use black to re apply lines between armour when you make a mistake. This is a slow process so feel free to work on sections of the model one at a time., for each stage of the highlights you may need 2/3 coats to create a smooth transition.
