title: python conversion between color spaces
body: <p>I wanted to convert from rgb to hsv but the results seem to be unexpected</p>
  
  <p>Following is the code</p>
  
  <pre><code>   import colorsys
  
     print colorsys.rgb_to_hsv(144, 190, 255)
  </code></pre>
  
  <p>and it prints following</p>
  
  <pre><code>    (0.5, 0, 255)
  </code></pre>
  
  <p>where I was expecting it to be </p>
  
  <pre><code>    (215,44,100)
  </code></pre>
  
  <p>or      </p>
  
  <pre><code>    (215,0.44,1.0)
  </code></pre>
  
  <p>any idea???</p>
  
  <p>Thanks a lot</p>
