title: What are the Android naming conventions for colors with alpha?
body: <p>I have text color with alpha.<br />
  Is it good idea to name color like black_20 where 20 is 20% opacity?</p>
  <p>I would like to find some general convention which will work fine in bigger team with more exotic colors that most of people cannot immediately recognize by name.</p>
