Version: 3.5.6 (enterprise 20071221.751182) (using 3.5.8 "release 33.2" , openSUSE ) Compiler: Target: i586-suse-linux OS: Linux (i686) release 2.6.18.8-0.7-default With the last update of kontact from the enterprise branch my calendars got a completely different coloring. After some investigation I noticed that all calendar items without a category are colored with the ressource color instead of the default event color. This is new behaviour and came up with the last update from OpenSUSE 10.2 enterprise branch of kontact/korganizer.
This bug is now valid for the KDE 3.5 stable branch as well because the enterprise branch has been merged into 3.5.9.
In trunk r865573 this is changeable by right-clicking the resource and selecting "Disable colour" (makes it use the default instead). I think this is the expected behaviour.
