colors of my yahoo mail

I have this orange section on the top of my yahoo page and don't know how to change the color I also have some of the boxes blackened out, like the emoticons, format,spam 📎When_emailing_a_letter.PNG Hope someone can help. Now this page is going wacko on me. Oh well.

Click on the gear icon in the top right hand side
Then on click on theme
Then select your color and click save.
