编辑：颜色覆盖适用于我所拥有的一些按钮，其工作方式相同，除了我没有在主要样式资源中定义任何颜色，我只是设置颜色标签，但没有颜色属性
以下样式有3种颜色设置为整个样式中使用的默认颜色，但是如果我想在按钮上设置不同的颜色，我想要过度使用这3种颜色。
以下是ComboBox＆＃39; s，第一个应该是默认颜色，第二个应该是绿色覆盖。
<ComboBox HorizontalAlignment="Left" SelectedIndex="0" Text="Select USB Device">
<ComboBoxItem Content="Test 1" />
<ComboBoxItem Content="Test 2" />
<ComboBoxItem Content="Test 3" />
</ComboBox>
<ComboBox HorizontalAlignment="Left" SelectedIndex="0" Text="Select USB Device" Style="{StaticResource ComboBlue}">
<ComboBoxItem Content="Test 1" />
<ComboBoxItem Content="Test 2" />
<ComboBoxItem Content="Test 3" />
</ComboBox>

以下是用于覆盖颜色的样式，放置在主要样式之下。但由于某些原因，颜色没有变化。
<!-- Combo Box Colors -->
<Style BasedOn="{StaticResource {x:Type ComboBox}}" TargetType="ComboBox" x:Key="ComboGreen">
<Style.Resources>
<SolidColorBrush Color="{Binding Source={StaticResource NorGreen}, Path=Color}" x:Key="colour1" />
<SolidColorBrush Color="{Binding Source={StaticResource DarGreen}, Path=Color}" x:Key="colour2" />
<SolidColorBrush Color="{Binding Source={StaticResource LigGreen}, Path=Color}" x:Key="colour3" />
</Style.Resources>
</Style>
<Style BasedOn="{StaticResource {x:Type ComboBox}}" TargetType="ComboBox" x:Key="ComboGrey">
<Style.Resources>
<SolidColorBrush Color="{Binding Source={StaticResource NorGrey}, Path=Color}" x:Key="colour1" />
<SolidColorBrush Color="{Binding Source={StaticResource DarGrey}, Path=Color}" x:Key="colour2" />

答案 0 :(得分：0)
我设法找到解决方案，我使用了错误的资源类型。在引用我应该使用DynamicResource而不是StaticResource的颜色时。
