I mentioned this to Andy, but it may be on the back burner in terms of priority due to the fact that its regarding artistic things and not bugs or tangible features.
I suggested something along the lines of a 'default' style being generated by the menu that would look at your page's properties and if it found any, it would use them in the default style. Then any menus you did not set a style for would use this style. It would require you to specifically set the font colors and background colors in each page, and if it didnt find them, it would use some neutral default colors (milonics colors, hehe). But that way, each page would look like it had its own style of the menu, pulled right from the page.
Oh wait now, I just thought of something, Ruth. The menu has onclass and offclass, right? Well just have each menu item have its onclass and offclass set to the same css style (so its always a certain color or look). Then in each individual page, you set that css style up in the head of your document and that way the menu uses the colors of the style defined in that page! Each page defines the style differently, but the menu always looks for that one style by name and its different on each page.
There ya go, that should take care of it for you, I think.

But a default style might not be bad so people can just plug in a menu and not have to define a style if they don't want to.
