There are many many ways...you could forego sessions and drop a cookie with the color value in it; you could use the color as the session variable; if they are logged in via a database you could use the username as the session variable and drop their color code into the db using their session variable as a reference; sessions are a great tool, it just depends on how you want to go about it.

Something like:

<?php
session_start();
$bgcolor="#ffffff"; ## or whatever the user choose.
session_register("bgcolor");
echo "<body bgcolor=\"$bgcolor\">";
?>

if you want the color saved for future use, I'd suggest using a cookie, or a database wich it loads the user preferences from

cookie us just very easy. you should look at the PHP manual on how to set a cookie . 🙂 Btw, you should have some sort of signup and (members home) where they can set up their color preferences.. and after accepting the preferred color, you can then set it as a cookie with expiration time of 100 years 🙂

$expiration_time := time() + (3600 * 100)

SetCookie($colorPrefs1,"#thecolor",$expiration_time);
SetCookie($colorPrefs2,"#thecolor",$expiration_time);
SetCookie($colorPrefs3,"#thecolor",$expiration_time);

..
..

then, to read the cookie, you just need to access the variable $colorPrefs1 (whatever variable you assigned in SetCookie). to check if $colorPrefs1 contains a valid cookie value just test if it is empty 🙂
