No idea, we don't know what Ishibumi based it from. It could also be from the Gundam series in which Ishibumi reverses the usual trait from Gundam where the protagonist pilots a white Gundam while his rival pilots a red mobile suit into a main protagonist who is red while the rival is white. Ishibumi also based it from Pokemon too.
