Tell us what’s happening:

Your code so far

<style>
  .red-text {
    color: #ff0000;
  }
  .green-text {
    color: #00f000;
  }
  .dodger-blue-text {
    color: #2998e4;
  }
  .orange-text {
    color: #ffa500;
  }
</style>

<h1 class="red-text">I am red!</h1>

<h1 class="green-text">I am green!</h1>

<h1 class="dodger-blue-text">I am dodger blue!</h1>

<h1 class="orange-text">I am orange!</h1>

I think for the green, they are expecting #00ff00.

  .red-text {
    color: #ff0000;
  }
  .green-text {
    color: #00ff00;
  }
  .dodger-blue-text {
    color: #2998e4;
  }
  .orange-text {
    color: #ffa500;
  }
