faded background thing?, please help Options

[unspokenwords]

I know the code for the borders and background of the entries, i believe its this:
<style type="text/css">
table.blogbody {
background:#COLOR;
BORDER:#COLOR 2px solid; }
</style>

but what i can't find is a way to make the background of the texts, the color i want it to be, but faded like. i've seen it done before on people's xangas, but i really want the code.

please help?
