title: RGB to HSV is same as BGR to HSV?
body: <p>I am using OpenCV for colour space conversions. I was wondering if RGB to HSV conversion and BGR to HSV conversions will give me the same output?</p>
  <pre><code>cv2.cvtColor(np.float32(img),cv2.COLOR_BGR2HSV) # BGR to HSV
  </code></pre>
  <p>Because according to my assumption the only difference between RGB and BGR is a shift in channels, then by converting an RGB to HSV isn't it same as converting BGR to HSV?</p>
