colord-sane seems to be related to some printer utilities ("sane" =
scanner support)

I would have gone like...

~$ locate colord-sane		# needs mlocate package
/usr/lib/colord/colord-sane

~$ dpkg -S /usr/lib/colord/colord-sane
colord: /usr/lib/colord/colord-sane

So colord-sane is installed as part of colord package.

~$ apt-cache --installed rdepends colord
colord
Reverse Depends:
  cups-daemon
  cups
  cups-filters
  cups-filters
  cups-daemon
  cups
  colord-data
  colord-data
  libcolord2
  cups
  cups-filters
  cups-daemon

It is a cups *recommendation*, so you can uninstall it while holding on
to cups.

~# apt-get remove colord

However, if your printer can also work as scanner, then you may
actually need colord-sane in the future. So, instead of removing
colord, it is probably a better practice to disable colord-sane service
to see if it makes any difference. If it does, then you may debug why
colord-sane is stepping over the keyboard.
