RGB color combination to highlight landslide affected area

I have computed the backscattering coefficient (beta0 and sigma0 of both VV and VH) difference image ( by substracting pre event from post event and also by applying natural logarithm for ratio between post and pre event). Can anyone tell the RGB color combination, in RGB image window, to hightlight the landslide affected areas?

How about
Red= VV image 1
Green= VV image 2
Blue= VV difference

You don’t need Beta0 if you have Sigma 0.
