Here are some examples. The texture is still WIP and unfinished but gives an idea of what's possible.
The base texture:

I can easily apply a full single-colour scheme such as House Kurita red:

Or Liao green:

These full colour changes take only seconds to apply. More complicated would be common multi-colour designs like Steiner's assymetrical Blue and White, which would take a bit longer but perfectly possible:

And for people who don't like brightly coloured robots running around, we can also very easily do more militaristic schemes:


(This one looks really baller)
Or a combination even:

These are all done via Photoshop, not ingame or anything. What I can do is provide a variety of relatively easy-to-make schemes (after making the base texture) as prefabs. All that's needed is some ingame function/UI for players to choose which scheme they want.
