Color management has finally arrived at the GNOME Desktop. The new piece of software is called gnome color manager and is still pretty young. I heard about it while ago, so after installing Ubuntu 10.04 I found it in the repos and gave it a shot. It looks quite simple and promising. Still a bit unstable (crashes on some clicks) though. Unfortunately I couldn't calibrate my screen, because the color profile (ICC) I had for my screen was not suitable for full color calibration and I don't have any equipment to mesure my screen. But it's a good thing GNOME is getting a color manager, which it opens up to the professional Designers and DTP uses.
I made some screenshot for those interested.
