Note the Use system colors checkbox at the top of the tab. If this is checked, KMyMoney uses colors provided by the system, such as those associated with a selected theme, although the details depend on which operating system and possibly which window system or display manager is running. Very often, if you experience odd colors or odd combination of colors, toggling this checkbox will help.
