those values are indeed in the "all style options", however you just missed them, because in the color box you would see those background images that you have set.

For example, one of the values that I looked at in your style is this,

background: #869BBF url(images/gradients/blackgrey_tcat.gif) repeat-x top left;

You need to change the value #869BBF to a different color. That way, when your page is loading, before the background image is placed, you would see that color first.

Hope that helps.
