How to use the tooltip formatter and still display chart color (like it does by default)?

I found the documentation for this (http://api.highcharts.com/highcharts#tooltip.pointFormat). The HTML they’re using is located under pointFormat, not formatter:

<span style="color:{point.color}">\u25CF</span> {series.name}: <b>{point.y}</b><br/>

Here’s the updated code to use to get the colored circles in the tooltip:

tooltip: {
    formatter: function() {
        var s="<b>"+ this.x +'</b>';

        $.each(this.points, function(i, point) {
            s += '<br/><span style="color:' + point.color + '">\u25CF</span> ' + point.series.name + ': ' + point.y;
        });

        return s;
    },
    shared: true
},
