Your private color profiles should be stored in your user library:
Profiles installed for all users are in the systemwide Library folder
As you probably know, your User Library is hidden since Mac OS X Lion.
You can reveal it from the Finder's "Go" menu in the main menu bar:
Finder > Go
Then hold down to options-key ⌥, until Library appears in the drop-down menu. Select it and open the Library. Then look for the folder ColorSync/Profiles
