Style Manager Help

[jwashburn]

I am working on my first style. I have gotten the basics down, now I am tackling the Category Strip and the Table Header. The background for these two styles are gradient files preceeded by a hex color. For example the default for the Table Header is
#5C7099 url(images/gradients/gradient_thead.gif) repeat-x top left

While trying to learn how to make styles I figured I would just try and make a red Version of the default style. So I have created a red gradient and called it gradient_red_thead.gif and I have put it in the same directory as the default gradients.

I made the change in my style manager
#EF1C23 url(images/gradients/gradient_red_thead.gif) repeat-x top left

When I choose the style and view it on my board, its just turns the table header black.

What am I missing?
