just try with this

<pre><code> &lt;ProgressBar Height="25" IsIndeterminate="True" Width="150" Foreground="Red" &gt;&lt;/ProgressBar&gt;
</code></pre>

If it is not working as you required you have to modify the Style or ControlTemplate of Progressbar. 

To do that you can use Expression Blend from Microsoft or you can get a copy the existing template and modify it.

&lt;Setter TargetName="Animation"

</code></pre>



You can create your own style from original XAML or try to override background in the Loaded event for example:

<pre><code>private void ProgressBar_Loaded(object sender, RoutedEventArgs e)
{
 var p = (ProgressBar)sender;
 p.ApplyTemplate();

 ((Panel)p.Template.FindName("Animation", p)).Background = Brushes.Red;
}
</code></pre>

but it's unreliable

I came across a similar issue when the Windows visual settings were optimised for best performance (Control Panel -> System -> Advanced System Settings -> Advanced -> Performance -> Settings -> Visual Effects -> Adjust for best performance). The progress bar looked fine under normal settings, but horrible under "best performance". I just changed ForeGround to "LightGreen".

Here's what I saw on default ForeColor under normal conditions

Here's what I saw when adjusted for best performance

Here is the change

//after

Marat Khasanov pointed out that the unwanted green tint comes from the object named "Animation" within the control template. So another easy approach is to hide that object. This will also disable the animated "glow" effect, which I considered to be an asset but you might see as a deal-killer. I implemented this through a handler for the Loaded event as shown below.

This was inspired by <a href="https://stackoverflow.com/a/6940736/2998072">an answer to another question</a>. The same caveat applies: if they change the control template then this might no longer work.

<pre><code> public void ProgressBar_Loaded(object sender, RoutedEventArgs e)
 {
 var progressBar = sender as ProgressBar;
 if (progressBar == null) return;

 var animation = progressBar.Template.FindName("Animation", progressBar) as FrameworkElement;
 if (animation != null)
 animation.Visibility = Visibility.Collapsed;

 }

I found it rather useful to override the entire style.
You can pull the control template styles of any control with 

<pre><code>var yourcontrol = new ProgressBar();
// the control needs to load before it has a template.
yourcontrol.Loaded += (sender,e) =&gt; {
 var str = new System.Text.StringBuilder();
 using (var writer = new System.IO.StringWriter(str))
 System.Windows.Markup.XamlWriter.Save(yourcontrol .Template, writer);
 System.Diagnostics.Debug.Write(str);
};
// add it to your main grid, or some control thats loaded on screen.
gridMain.Children.Add(yourcontrol);
</code></pre>

Does anybody know how to change the foreground color of a WPF-Progressbar. It always seems to be merged with green.

有谁知道如何改变一个WPF-Progressbar的前景颜色。它似乎总是与绿色融合在一起。
