Let's set some better colors for the PushButton widgets.
Widgets each have their own group in the theme file, followed by several optional keys. To set the background and foreground colors you use the keys "Background" and "Foreground" ;) So to set the colors for a PushButton you would use the following:
[KDE]
widgetStyle=basicstyle.la
Copy it over to your theme config directory, run settheme, and check it out. You will find all widgets use this general format - the widget name as the configuration group (ie: [PushButton]), followed by several keys to configure it.
In the next section we will look at how to utilize KDE's built-in gradient engine for speedy gradient widgets.
