How to do Los on mi jsa.bases? Those are the colours of my mishima kieretsu I have no ideas on my mind at the Moment. https://imgur.com/gallery/LeZa13b
To continue with the combination of white/light gray of the armor with the blue of the pants, you could paint each half of the base with one of those colors. which one for the front and which for the back... in my opinion better the lighter color for the front.
I just went with red/white bands on my JSA. Red for the forward arc, white for the back. But I use the basic red/white/black colour scheme for mine.
