I must admit, this is much harder to handle in jAlbum than at the source of the problem.
Exactly. I don't know LR, but can't you get it to stop writing the "colors" to that
xmp field? Even better, get it to write the information you
do want to
xmp.dc:title[1], which jAlbum uses by default.
${xmp.xmp:Label} ${comment}
