Funny Square-2 parity

[Kickflip1993]

I solved my square-2 for the first time, and after solving, the colour scheme was switched^^
2 opposite colours have to switch, but the middle layer is done.
Btw. what would be the best stuff to fill the square-2?
It is going to be on ebay in about an month.
i think it is the third or fourth one in white.

Treat the two sides as four right-triangle slices-of-3.

EDIT: I think this is the simplest: Assuming the split runs BR-FL-ish: (-1,0) / (-3,3) / (-3,3) / (AUF, ADF)
