I'm not sure what you mean.

For the game supermechs there's only the option of colouring your mech through fusion if you want it done free.

However, colouring your mech doesn't effect any actual gameplay, so it's a nice lil feature for the supporters of the game. Rather this than making only supporter exclusive weapons heh? The most you could try aim for is some of the basic colours at a very high price xD still I don't know if they'd go for that either.
