title: How to change css color scheme by applying hue change co all colors in css file
body: <p>I have a css file and i want automatically create few color variations of the file, using something like "colorize" in GIMP to shift hue of template. </p>
  
  <p>I found something that does exacly what i want: <a href="http://adityabhandari.com/wp-content/uploads/2011/01/ColorChanger.html" rel="noreferrer">http://adityabhandari.com/wp-content/uploads/2011/01/ColorChanger.html</a> 
  but it not support <code>rgba()</code> notation i often use. </p>
  
  <p>I'm linux user so maybe some tricky shell script with regex will do, problem is i really suck at regex. </p>
  
  <p>If you post <code>php/python/awk</code> solution I'm smart enough to use it to.</p>
