Before I left openSUSE I had an little idea how to bring color managment on the Linux desktop forward. If you use colord or Oyranos on the end you will need always ICC-profiles. On ubuntu you can install the package icc-profiles and you will have the most profiles for printing jobs mostly from Adobe. For Fedora and openSUSE you have to download them from Adobe. But this is easy against finding profiles from some hardware manufacturers. Sometimes it is an adventure to finde them, I can tell you that. It should be easy to build a platform for sharing free profiles and if there is an API applications can download them from there.
Now its not really only an idea anymore.
Last summer Sebastian Oliva worked as GSoC student on it, now the main parts are done. Also dispcalGUI integrated the service in his last version. But there is still some work todo. XOrg and ICC share on FOSDEM an DevRoom and on sunday there will be a lot of color managment talks and I will present the status of Taxi DB
