Two ways - make them hidden fields on each page (only works if you're
using forms), or store each one in the $_SESSION superglobal, i.e.
<?php
session_start();
$_SESSION['color'] = $_POST['color'];
?>
And when you want to use it:
<?php
session_start();
$color = $_SESSION['color'];
?>
Of course you will want to validate the entries to ensure they exist,
contain valid values, etc. (never assume $_POST data is accurate!).
But hopefully you get the idea.
