I tried to look at the image band by band, but got three
grey-scale-looking images (for r, g, and b), and one white one.

I have a feeling my clue lies in the latter, but am having a hard time
finding examples of how to manipulate that part (trying hard to avoid a
spoiler here!) in the documentation.  Any pointers? (if anyone can even
understand what I'm trying to ask here, ha ha!)
