body: <p><a href="https://i.stack.imgur.com/oJ2ah.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/oJ2ah.png" alt="enter image description here"></a></p>
  
  <pre><code>&lt;TextField
      id="standard-full-width"
      label="Password"
      style={{ margin: 8 }}
      fullWidth
      margin="normal"
      placeholder="*******"
  /&gt;
  </code></pre>
  
  <p>I'm not able to figure out how to change the color of the label and the underline when the focus is activated on the input field.</p>
  
  <p>Some advice?</p>
