I have followed this great tutorial on pan sharpening using Grass GIS 7 (I'm using beta 3). Everything in the tutorial seemed to have worked, but my final output is not as expected (pictured below).
I tried with various sharpening methods, colour balancing stages and with and without atmospheric correction. I also tried with different images.
Any advice on where I'm going wrong?
Here's the output from r.univar:
