title: find lighter and darker colors based on any color from white to black
body: <p>Can any one tell me how can I do same as  <a href="http://0to255.com/" rel="nofollow">0to255</a> in a Windows Store app (C#)?</p>
  
  <p>In short I need a logic in which I will pass a color &amp; it will give me a list of color.</p>
  
  <pre><code>private List&lt;string&gt; GetColorCollection(string hexcolor)
  {
      //TODO: 
  }
  </code></pre>
  
  <p><code>GetColorCollection(510099)</code> should give me the result same as <a href="http://0to255.com/510099" rel="nofollow">this</a>.</p>
