Use Hex Code to Mix Colors Errors

In the challenge “Use Hex Code to Mix Colors”, I keep getting the error -" Your h1 element with the text I am red! should be given the color red" for all four colours. Can someone help me with this?

My code so far

.red-text {
  color: #FF0000;
.green-text {
  color: #00FF00;
.dodger-blue-text {
  color: #1E90FF;
.orange-text {
  color: #FFA500;

<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>

Yup was the dark mode extension. Thanks for the help!
