Also I went through all changes made between 1.0.25 and 1.0.27 with regards to genesys in general and more specifically gl847 (which is the chip CanoScan LiDE 100 is using) looking for anything related to colour. The only thing I was able to find was this patch changing reallocation of gamma tables: https://anonscm.debian.org/cgit/sane/sane- backends.git/commit/backend/genesys.c?id=5edb87f9ac950473f8c3a57b4071c970887d8440
