title: UIColor preview tool?
body: <p>Say I have</p>
  
  <pre><code>UIColor *blue = [UIColor colorWithRed:0.65 green:1.0 blue:1.0 alpha:0.8];
  </code></pre>
  
  <p>Is there any online tool I can use to preview this values, so I can find what color I want exactly. Im not sure what these decimals are called. Its not RGB or hexadecimal so I dont know what it is..</p>
