How to change the color of the text on the Tab interaction.

Hi,

I'm using Engage 09 and have created an color scheme for my Tab interaction.  What I can't figure out is how to change the color of the font on the actual tabs in the Color Scheme Editor.  The text on the 5 tab buttons on the left is white, and I would like to change it to dark grey or black.  If this is done in the Color Scheme Editor, I have not been able to figure it out.   How do I make this change?

Thanks in advance!
