This would be very easy using jQuery. Just include the library along
with something like the following:

$(function()
{
$('#id_of_your_select').change(function()
{
var status = $(this).val();

if (confirm('your confirmation message'))
{
$.ajax({
url: '/path/to/controller/action',
data: 'status='status,
success:
function(html)
{
// do something with returned color data
}
});
}
});
});

The above could be saved to a separate file and included in the view like so:

echo $javascript->link('jquery.min', false);
echo $javascript->link('some_file_name', false);

If you'd rather pass the status as an action parameter, leave out the
'data' option and change url to:

url: '/path/to/controller/action/' + status
