This link sends me to 
www.linuxcompatible.org/Eye_of_GNOME_2.11.90_s51920.html
which tells me the following

ICC color profile support, requires the Little CMS library 
available at http://www.littlecms.com/ (Ross Burton)

Putting the cursor  on the word support  (which is green and double
underlined) brings up an ad for AT&T Tech Support 360, and clicking on
the word support takes me there.  Once I get there, I don't see what if
anything to do to find out about eye of gnome color management.  (In
fact, placing the cursor on any link in green which is double underlined
on that page brings up an ad.  I've never seen anything like that.)

I haven't been able to find any detailed explanation of how eye of gnome
supports color management.  I would expect there to be some settings
which one could modify.  I'm pretty sure the version I have
(eog-2.22.3-1.fc9.i386) is not using my display profile.

I could of course compile eog from source and hope for the best, but I
would like some more information first.
