title: Border Color in InputBase in React Material
body: <p>I need to put a <code>borderColor</code> in my <code>InputBase</code> in my react material. I tried to do the code below and it still doesn't appear.</p>

  <p><strong>CODE</strong></p>
  <pre><code>import palette from &quot;../palette&quot;;
  
  export default {
    focused: {
      borderColor: palette.primary.main,
      borderWidth: 10
    }
  };
  </code></pre>
