You could use a GradiantBrush and set the GradientStops based on your logic, the only downside to this solution is that GradientStops aren't bindable so you have to set them from code. Here is a simple taste:

 <ProgressBar Width="500" Value="70" Height="30">
        <ProgressBar.Foreground>
            <LinearGradientBrush StartPoint="0,0" EndPoint="1,0" >

                <GradientStop Color="Green" Offset="0" />
                <GradientStop Color="Green" Offset="0.3" />
                <GradientStop Color="Red" Offset="0.3" />
                <GradientStop Color="Red" Offset="0.5" />
                <GradientStop Color="Green" Offset="0.5" />
                <GradientStop Color="Green" Offset="1" />

            </LinearGradientBrush>
        </ProgressBar.Foreground>
    </ProgressBar>

Output:
