You set the style for the markers.state.select as:

    plotOptions: {
        series: {
            allowPointSelect: true,
            marker: {
                states: {
                    select: {
                        fillColor: 'red',
                        lineWidth: 0
                    }
                }
            }
        }
    }

Update: For barcharts the configuration should be slightly different (don't know why really):

plotOptions: {
    series: {
        allowPointSelect: true,
        states: {
            select: {
                color: 'red'
            }
        }
    }
}
