title: How to color ticktext in plotly?
body: <p>I would like to display my ticktexts in my plotly xaxis with different colors based on the respective string (based on a dictionary).
  Is there a functionality in plotly to do this, maybe via HTML coding?</p>
  
  <pre><code> ticktext = ['&lt;font color="red"&gt;{}&lt;/font&gt; '.format(x) for x in ticktexts]
  </code></pre>
  
  <p>doesn't work, it gives the html string to the labels. </p>
