Blaze can't be Fire+Lightning because nothing within Blaze has any characteristics of Lightning. If its not a Fire-Yin mix, it could be Yin enhanced Fire.

Kakashi enhanced Raikiri with Kamui. Son Goku's fire is green u.u http://img2.wikia.nocookie.net/__cb20150223072612/naruto/images/thumb/4/40/Monkey_Flame_Arson.png/640px-Monkey_Flame_Arson.png
