title: How do I set background color in libgdx?
body: <p>I am trying to make the background a sky blue color with RGB of 135,206,235.
  When I run it, the background is not the color I expected.</p>
  <pre class="lang-java prettyprint-override"><code>public void render () {
      Gdx.gl.glClearColor(.135f, .206f, .235f, 1);
      Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
      batch.begin();
      batch.draw(img, 0, 0);
      batch.end();
  }
  </code></pre>
