title: react-native TouchableHighlight disable onPress color flickering
body: <p>I want to disable the "color blink" or "color flickering" effect that blackens the image when TouchableHighlight gets pressed.</p>
  
  <p>Here is the screen render:</p>
  
  <pre><code>&lt;TouchableHighlight onPress={this._onPressButton}&gt;
                    &lt;Image
                    source={require('../../img/fish.png')}
                    style={[styles.iconSize, styles.iconMarginRight]}/&gt;
  &lt;/TouchableHighlight&gt;
  </code></pre>
  
  <p>How do i accomplish that? </p>
