Code is correct not passing

Welcome, cconu.

The issue is the spelling you have used for grey. You will need to use the American version gray to pass the tests.

For future posts, if you have a question about a specific challenge as it relates to your written code for that challenge, just click the Ask for Help button located on the challenge. It will create a new topic with all code you have written and include a link to the challenge also. You will still be able to ask any questions in the post before submitting it to the forum.

Thank you.
