title: Call Winforms ControlPaint.Light() in WPF project
body: <p>I have a <code>Brush</code> object that I want to lighten using the Windows Forms <code>ControlPaint.Light()</code> method.</p>
  <p>I want to convert a <code>System.Windows.Media.Brush</code> object to <code>System.Drawing.Color</code> so that I can change any XAML button background color to its &quot;light color&quot; on button click, because <code>System.Windows.Forms.ControlPaint.Light()</code> takes only color as argument.</p>
  <p>Since my <code>Brush</code> object is not a <code>SolidColorBrush</code> and so does not have a <code>Color</code> property, is there some alternative to achieve this?</p>
