FWIW, how I would probably handle this is to have an array of
$people_from and an array of $state_colors and then serialize() them and
run through urlencode().  Then you have an array on the next page.  Much
easier to work with:

$people_from = array('K-Alfalfa', 'OK-Atoka'); //etc...
$state_colors = array('#FFFFCC', '#FFFFCC'); //etc...

Then the link would be:

$url =
'generic.php?people_from='.urlencode(serialize($people_from)).'&state_colors'.urlencode(serialize($state_colors));

You then have a $_GET['people_from'] and $_GET['state_colors'] array on
the next page.
