Sure... just style the container, and inherit from the skin.css.
Here's how I do it:
Say your container is named "blue".
In the html table definition, add:   class="blue":
<table border="0" cellpadding="0" cellspacing="0" class="blue">

In the container css, set up a blue class:
.blue {background-color: blue}

Then, you can style like this:
.blue .Head {color: white}
.blue .Normal {color: white}
or, combine them:
.blue .Head, .blue .normal {color: white}

If you have the head and normal classes set to black or whatever in the skin css, it will be overridden (to white) in your blue container.

Hope I explained this understandably...
