Thanks for answering :). First of all, I didn't install any additional packages related to Gutenprint, CUPS or other GUI for configuring my printer. All I have is Ubuntu-Desktop. I don't think this bug is related to an already existing bug because it's really "only" about the colors. I don't experience any other problems except the bad colors. I have an up to date Feisty Fawn, so the Gutenprint version is 5.0.0.99.1-ubuntu2 (feisty). I also attached my PPD file. I hope this helps.
