How to Change color of Progress bar

I Wish to use this progress bar, but i don’t know how to change the color of this, to Black but i failed to use " foreground color " when I was trying to use this style.

This error shows up

Here is the Code I used.

  <ProgressBar HorizontalAlignment="Left" Foreground="Azure" Value="50" Style="{StaticResource ProgressBarPrimaryStripe}" Height="18.8" Margin="542.4,410.4,0,0" VerticalAlignment="Top" Width="211.6">
        <ProgressBar.RenderTransform>
            <TransformGroup>
                <ScaleTransform/>
                <SkewTransform/>
                <RotateTransform/>
                <TranslateTransform/>
            </TransformGroup>
        </ProgressBar.RenderTransform>
        </ProgressBar>

just use these codes :

<ProgressBar Style="{StaticResource ProgressBarPrimaryStripe}" Value="50">
    <ProgressBar.Resources>
        <Color x:Key="DarkPrimaryColor">Black</Color>
    </ProgressBar.Resources>
</ProgressBar>

@AdarshRise you can do like this

<ProgressBar Value="50" Style="{StaticResource ProgressBarPrimaryStripe}">
           <ProgressBar.Foreground>
               <DrawingBrush Viewport="0,0,20,32" TileMode="Tile" ViewportUnits="Absolute" Stretch="None">
                   <DrawingBrush.Transform>
                       <TransformGroup>
                           <RotateTransform Angle="20"/>
                           <TranslateTransform x:Name="MyTransform" X="0"/>
                       </TransformGroup>
                   </DrawingBrush.Transform>
                   <DrawingBrush.Drawing>
                       <GeometryDrawing>
                           <GeometryDrawing.Brush>
                               <LinearGradientBrush EndPoint="1,0" StartPoint="0,0">
                                   <GradientStop Color="Black" Offset="0"/>
                                   <GradientStop Color="Black" Offset="0.5"/>
                                   <GradientStop Color="White" Offset="0.5"/>
                                   <GradientStop Color="White" Offset="1"/>
                               </LinearGradientBrush>
                           </GeometryDrawing.Brush>
                           <GeometryDrawing.Geometry>
                               <RectangleGeometry Rect="0,0,20,32"/>
                           </GeometryDrawing.Geometry>
                       </GeometryDrawing>
                   </DrawingBrush.Drawing>
               </DrawingBrush>
           </ProgressBar.Foreground>
       </ProgressBar>
