I use this codes by "juggledad"
I put it at window "Add HTML/CSS Inserts->CSS Inserts".
1.---------------------
body.home td#middle {
background: #red;
}
body.home.paged td#middle {
background: #yellow;
}
----------------------
But only BG-colour of homepage have changed.
All paged pages have Main BG.
2.---------------------------------------
div.category-red-wine {background: #red;}
div.category-books {background: #blue;}
div.category-white-wine {background: #yellow;}
-----------------------------------------
No results.
P.S Be patient, pls, I am beginner.

NOTE by Juggledad: The use of #yellow or #red works in some browsers and not in others, so use eithor the color name without the # or the hex RGB value with the # ie '#00FF44'
