Excel 2007 : Tab text color problems

Hi everyone.

In a spreadsheet I've been working on, the person who initially created it did something to the worksheet tabs--I think maybe they first grayed them out and then ungrayed them somehow--and now the modified tab titles have black text, whereas all the others are the traditional blue.

We can't seem to figure out any way to alter the text color using normal methods. Do you guys have any ideas on how we can switch the black back to blue?

Thanks for your help!

Thank you, sir! Worked perfectly.
