Use Hex Code to Mix Colors again

1

I can’t see what I’m doing wrong. It’s the end of a long day and I will come back to this tomorrow. I have spent ten minutes on it and can’t see whats wrong.

Can you help me please?
Thanks

Your code so far

<style>
  .red-text {
    color: FF0000;
  }
  .green-text {
    color: 00FF00;
  }
  .dodger-blue-text {
    color: 2998E4;
  }
  .orange-text {
    color: FFA500;
  }
</style>

<h1 class="red-text">I am FF0000!</h1>

<h1 class="green-text">I am 00FF00!</h1>

<h1 class="dodger-blue-text">I am 2998E4!</h1>

<h1 class="orange-text">I am FFA500!</h1>
