title: Identifying the range of a color in HSV using openCV
body: <p>I am working on identifying the color yellow using openCV in python. I have come to this step where I have to define the lower and upper range of the color yellow in HSV.</p>
  
  <p>Example for defining the range of Blue:</p>
  
  <pre><code>lower_blue = np.array([110,50,50])
  upper_blue = np.array([130,255,255])
  </code></pre>
  
  <p>The HSV is usually defined in percentage, I want to know how to define the range for yellow like the example.</p>

  <p>Edit:
  There are some suggestions in the blog mentioned above, but it does not give me the desired output.</p>
