how to make different marker/ color for multiple address?

Hi.,.
thanks for the code.
I try to change the marker/ color for multiple addrees, but not success.
like:
$gm = & new EasyGoogleMap("map-key");
$gm->SetMarkerIconStyle('PUSH_PIN');
$gm->SetMarkerIconColor('PACIFICA');
$gm->SetMapZoom(13);
$gm->SetAddress('address1');

$gm->SetMarkerIconStyle('PUSH_PIN');
$gm->SetMapZoom(13);
$gm->SetMarkerIconColor('GRANITE_PINE');
$gm->SetMarkerIconColor('PACIFICA');
$gm->SetAddress('address2');


any idea how to do this?

thanks for any reply/ help
