Changing backgroundcolor of tooltip for a specific data point in Highcharts

I have a Highcharts line chart and have tooltips enabled, however, I would like to change the background color of tooltip for just a single data point on the chart.
Is it possible to do so?
What I have so far
tooltip: { formatter: function () { return this.y; }, backgroundColor: '#68BD49', borderColor: '#000000', borderWidth: '1' },

Yes it is possible, by using HTML option and define custom parameters. Obviously you can use CSS styles / classes disable padding/margins, but in the simplest way you can achive this in this way: 

 tooltip: {
        useHTML:true,
        formatter: function() {
            console.log(this);
            if(this.point.customBck)
                return '<div style="background-color:red;">The value for <b>'+ this.x + '</b> is <b>'+ this.y +'</b></div>';
            else
                return '<div>The value for <b>'+ this.x + '</b> is <b>'+ this.y +'</b></div>';
        }
    },
