title: C# WPF Token is not valid on BrushConverter
body: <p>I am converting a System.Media.Brush to a System.Drawing.Brush, but after I change the color. It throws a "Token is not valid" error on the converter.</p>
  
  <pre><code>    private Brush DrawingColorToBrush(System.Drawing.Color color)
      {
          Brush ret;
  
          BrushConverter m;
  
  
          m = new BrushConverter();
          ret = (Brush)m.ConvertFromString(color.ToArgb().ToString("X8"));
  
          return ret;
      }
  </code></pre>
  
  <p>The color is coming from a System.Windows.Forms.ColorDialog
