Someone would have commented on it, either Sanji or Queen. It seems brighter flames and white lightning effect are the only new features to portray hotter flames. Blue flames with orange lightning would be awesome but yeah, not happening.
I don't understand why the "white hot" thing is brought up so often when the original language is Japanese.
It only makes sense for it to be blue sense sense the temperature is much hotter but it could also be white flames because he said he was stocking white hot , but white flames with a Lil blue around it is bad at all:cheers:
