Well G1 piranahcon kinda have that vibrant color scheme..... but seeing God neptune, I kinda like his clean coloring of white and gold. Although your Gestalt might end up looking boring in God Neptune colors, So go for the G1 instead, I think that properly executed it blends well. Like one example of colouring that can break an otherwise nice figure is TFU powerglide - hasbro version.
These must be really huge figures. Heavy too!
