title: theme() from Tailwind is not recognized
body: <p>I know it may be a silly question but I cannot find the answer anywhere.
  I'm using Tailwind with CRA and CSS modules.</p>
  <p>I've overwritten the default theme colors to my own ones.
  When I try to use the colors inside my CSS modules like this,</p>
  <pre><code>.amountSign {
      color: theme('colors.pink');
  }
  </code></pre>
  <p>it seems like theme() is not recognized and in the browser the property value seems to be invalid.</p>

  <p>Should I import something from somewhere to make theme() recognizable? Thanks in advance</p>
