In addition to the per-widget color settings you can also include a subset of the standard KDE color scheme with your theme. This will be applied to all widgets that lack a configuration. It also contains the "contrast" key, which controls how bright and dim the non-pixmapped highlights are. These keys are the same used in normal 1.x color schemes.
The "contrast" key goes into the [KDE] group, while the colors go into the [General] group and contain the following keys:
Key | Description |
foreground | Foreground color |
background | Background color |
selectForeground | Selected text foreground color |
selectBackground | Selected text background color |
windowForeground | Window foreground color |
windowBackground | Window background color |
