title: How to change the colour of the bounding box in opencv SelectROI function
body: <p>I been looking everywhere on how to change the color of the bounding box that comes with the SelectROI function.</p>
  <pre><code>bbox = cv2.selectROI(frame, False)
  </code></pre>
  <p>The default bounding box is of the blue color but the videos I am doing on need a different colour such as bright red or orange.</p>
  <p>I would really appreciate if anyone could point out on how to do it. Thanks in advance</p>
