Kamehameha's Colour

[Kaboom]

My theory is that if for example your aura is blue but then you go SSJ and then your aura turns yellow, maybe so does your ki attacks. But the original is Blue, the SSJ version is Yellow and the GT SS4 is red.

Goku, while at various SSj levels, has fired more blue Kamehamehas than practically everybody else combined.

Let's not forget Gohan and Cell's famous Kamehameha vs. Kamehameha struggle. There was plenty of blue going on there, and they were both Super Saiyan level 2.

Or Cell's equivalent thereof.

I know, but my point was Goku being the undisputed master of SSj Kamehamehas.
