Challenge: Learn CSS Colors by Building a Set of Colored Markers - Step 49

Link to the challenge:

So I clicked on the challenge link you provided, and using the code you had, the test passed:

.red {
  background: rgb(255, 0, 0);
}

Are you saying you get an error when you try to submit that? If that code fails when you try to submit it, might be a cache or browser issue.

yes it keeps saying not correct and I rest the test page more the once but not the browser.
