title: Convert an RGB image to Oklab Color Space
body: <p>I have an image loaded using <code> cv2.imread</code>  command in <code> RGB</code>  format.  Is there a fast conversion/implementation of converting it to <code> oklab</code> color space?</p>
  <p>Tried colour-science package, however, there are problems with import and I can't explore.  The colorio on the other hand doesn't show an explicit explanation.</p>
  <p>Please see <code>oklab</code> description <a href="https://bottosson.github.io/posts/oklab/" rel="nofollow noreferrer">here</a>.</p>
