title: HSV OpenCv colour range
body: <p>Can anyone please tell me a name of a website or any place from where I can get the  upper and lower range of HSV of basic colours like</p>
  
  <blockquote>
    <p>yellow,green,red,blue,black,white,orange</p>
  </blockquote>
  
  <p>Actually I was making a bot which would at first follow black coloured line and then in the middle of the line there would be another colour given from where 3 different lines of  different colour gets divided.The bot needs to decide which line to follow.
  For that I need the proper range of hsv colours</p>
