Kamehameha

Seriously it's honestly kinda funny how these signature moves(kamehameha ,rasengan and Getsuga tensho) were all Yellowish -white (kamehameha)/Gold

Not gonna lie good change(except for getsuga tensho glad the anime changed it back)

Now this might sound weird but hear me out.

I've always classified Kamehameha (and versions of it) in 2 ways...

1: The Brick Wall, the enemy just gets dragged along and take Impact damage instead of being torn apart. (Example the 4x Kaioken Kamehameha vs Vegeta in the Saiyan Saga)

2: The Tear Apart Kamehameha, the enemy gets ripped apart instead of taking impact damage also usually the beam goes through them instead of eventually stopping. (Example the Father-Son Kamehameha vs Super Perfect Cell during the Cell Arc)

Why is this the case? Why aren't all Kamehameha (and it's variants) the same?
