Set SelectedColor = Red in XAML or code behind or via databinding. Open the color Picker - the red color in Standard Colors is NOT selected but it should be.

A possible workaround could be:

   <Style TargetType="telerik:RadColorPaletteView">
         <Setter Property="SelectedItem" Value="{Binding MediaColor, Mode=OneWay, RelativeSource={RelativeSource AncestorType=telerik:RadColorSelector}}" />
   </Style>
