2 color 3x3 help

[tacobellcustomer101]

So I tore off the stickers of a 3x3 and recolored it so that up right and front are blue and back down and left are red.
So far I solved it as a regular cube, but two of the corners got switched just like on the 4x4. What algorithm can I use to switch the two adjacent corners?

Try using a j-perm with the diagonal dividing the colours facing FL to BR

R-perm?
