我猜Expander控件有一个Background属性，它通过TemplateBinding绑定到它的嵌入边框控件：
<Border x:Name="Background" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="3">
<Grid>
<Grid.ColumnDefinitions>
...
尝试通过在扩展器样式中添加以下行来设置扩展器控件的相应Background属性（用您的颜色替换＃000000）：
<Setter Property="Background" Value="#000000"></Setter>
希望有效， 欢呼声
