title: WPF Progress Bar in different colors
body: <p>I am having a alarm status. I want to reflect the alarm status on the progress bar with the help of colors. 
  If an operator has handled the alarm till 30% status, so Progress Bar will show the 30% color and if Operator has handled till 60%. So Progress Bar will show the first 30% in red color and then next 30% in blue color.</p>
  
  <p>I am setting the value of the progress bar to 30 and getting green color. My question is when i want to set it to 60% it will show green for first 30% and red for next.</p>
