title: How to find the RED color regions using OpenCV?
body: <p>I am trying to make a program where I detect red. However sometimes it is darker than usual so I can't just use one value.
  What is a good range for detecting different shades of red?
  I am currently using the range 128, 0, 0 - 255, 60, 60 but sometimes it doesn't even detect a red object I put in front of it.</p>
