FIRRIB
From MediaWiki

FIBRIR stands for "Frenzy is blue, Rumble is red". Likewise, RIBFIR means "Rumble is blue, Frenzy is red". (The forms FIRRIB and RIRFIB are also known.)
The entire debate exists because "RIBFIR" in the American G1 cartoon, but "FIBRIR" in the toyline, comics, the Japanese G1 dub (which simply switched who was who), and even the US cartoon bible.

It is generally agreed that pointing out Rumble was actually kinda purple in the original cartoon is not helpful.
