install ImageMagick (yum install ImageMagick), then something like this:
$ compare aaa.png bbb.png -highlight-color violet \
-lowlight-color darkgray -compose threshold jpg:- \
| convert jpg:- -fuzz 2% -fill red -opaque '#915e99' \
png:cmp-aaa-bbb.png
will generate cmp-aaa-bbb.png effectively diffing bbb.png against aaa.png
NB: see also img-diff in dotfiles.git/.bashrc
