Function that changes text color with button [closed]

I want this HTML button to change the color of my text in order to show/hide it.

div info is a timer that it’s JavaScript function decreases time. It’s ID in the JavaScript file is gameTime30.

function changeColor(info) {
  const info = document.getElementById(element = 'info');
  if (info.style.color == "#333") {
    info.style.color = "#EE0000";
  } else if (info.style.color == "#EE0000") {
    info.style.color = "#333";
  }
}
<div id="info">30s</div>
<div id="buttons">
  <button id=newGameBtn type="submit" onClick="window.location.reload()">↺</button>
  <button id=thirty onClick="changeColor('info')">30s</button>
</div>
