cool, for the Blue,
Start with Regal Blue, then highlight with shades of enchanted blue, wash with blue wash and babab mixed, then blend in between down to chaos black in the recesses.
Highlight up to white on the raised edges.
Enchanted Blue is the key , it seems to work very well in it's own right without much work.
My armour technique is learned over time experimenting , i use white spray undercoat, and base with boltgun + vermin brown 60/40 mix, then wash with babac , then a layer of red wash, then gryphon, then devlan mud, then a blue wash in the recesses , highlighting with a watered down mithril and up to very thin white lining .
A good trick for the yellow is to start with a washed down layer of snakebite leather as the base on top of white,
then shade upwards after washing with gyrphon
