How to change the text of buttons in ColorPicker

How can I change the text or size of the confirmation button in ColorPicker?
It doesn't look good right now. In my language, the text does not fit in the button.

Increasing the width of the ColorPicker doesn't help either.
As far as I understand, the only thing I can do is completely override the style for the ColorPicker?

I was able to solve the problem by hiding part of the ColorPicker and inserting my buttons in front of the Popup. Maybe this will help someone. I haven't found a proper solution, but this crutch at least works.

              <StackPanel>
                  <hc:ColorPicker x:Name="HcColorPicker" Width="240" Height="295"/>
                  <Button x:Name="Canceled" Content="Отмена" VerticalAlignment="Top" HorizontalAlignment="Left" 
                          Height="30"  Width="90" Margin="20,5,0,0"  
                          Click="ColorPicker_Canceled"></Button>
                  <Button x:Name="Confirmed" Content="OK"    VerticalAlignment="Top" HorizontalAlignment="Left" 
                          Height="30"  Width="90" Margin="130,-30,0,0"  
                          Background="#326cf3"
                          Foreground="White"
                          Click="ColorPickerOk_Click"></Button>
              </StackPanel>
