title: Annotation color only shows when text outside of Google Bar Chart
body: <p>I have a google <a href="https://developers.google.com/chart/interactive/docs/gallery/barchart" rel="nofollow noreferrer">bar chart</a> and I am setting the font size and the color, however the color only applies when the text is outside of the bar.  How do I force the color to apply? </p>
  
  <pre><code> annotations: {
          textStyle: {
            fontSize: 18,
            color:'#000000'
          }
        }
  </code></pre>
