Version: 1.11.2 (using KDE 4.2.2) OS: Linux Installed from: Mandriva RPMs In KMail 1.11.2 the background of the lines of the messages list are alternatingly white/blue. I find that quite annoying. I request an option to display the messages list with a white background and not that white/blue/white/blue... thing.
Alternating background in list views is a standard KDE thing. You can change the color for the in the system settings.
Thanks Thomas, systemsettings->Appearance->Colors->Colors->View>Alternate Background: I changed it first to complete white. But then in konqueror file browser it is harder to detect the size and date of a short file name. So I changed the Alternate Background to a very light blue (Red:247, Green:247, Blue:255). That way I can still figure out in konqueror file browser size and dates and the message list of my kmail now no longer has that aggressively alternating background color.
kmail still has alternate colourings, see https://bugs.kde.org/show_bug.cgi?id=225048
