It's because Jolt was colored orange-ish in the cartoon, so Hasbro opted for show-accuracy.Seeing it in action, this is pretty clever: this one, single Jolt isn't too yellow for Hot Shot, and not too red for Powerlinx Hot Shot, since he falls in the middle.
And I don't say that just because I love orange.
