Using a camo scheme helps you use simple colours without it looking too much like an undercoat only. I did a similar scheme tio Brother SRM, except I used black as a base coat. Full block white armour kinda works against the idea of camouflage, unless the architecture favours solid white buildings, which could happen I guess. Very mediterranean
You can still shade the base-coat as normal and then stick on your disruption pattern. Popping colours are restricted to weapons and sensors in my scheme.
