Why Its Not Working

  body {
    background-color: black;
    font-family: Monospace;
    color: green;
  .pink-text {
    color: pink;
<h1 class="pink-text blue-test">Hello

Do you know the name of this particular FCC challenge?

Correct me if I am wrong but this is the challenge you are on

Now your issue is that your blue-test class is unnecessary because it overrides the pink text which is what the challenge is asking for delete that and you are good to go. Remember the challenge wants you to override the color: green command not a command of your own.
