title: Syncing two colors using jQuery or JavaScript?
body: <p>If I have two colors, let's say <code>Red (#ff0000)</code> and <code>Dark Red (#850000)</code>. Is there a way to make it so that when one color is changed, the other changes accordingly?</p>
  
  <p>So for example if I change Red into Blue, Dark Red automatically changes to Dark Blue and so on..</p>
