>>5333347On the topic of Combiner colors, I think it depends on what colors are used, and if those colors are aesthetically pleasing.
For instance, God Neptune of BWII has a uniform color scheme of white, teal, gold, silver/grey, and brass. It looks good!
It could also do something with the individual personalities. Superion's more uniform color represents the Aerialbots' unity, while Menasor's clashing colors represents the Stunticons' hatred towards Motormaster.
