@shweta-jagtap,

You can change the color of column using color property of dataPoint as shown in the code snippet below –

function setColor(chart){
	for(var i = 0; i < chart.options.data.length; i++) {
  	dataSeries = chart.options.data[i];
  	for(var j = 0; j < dataSeries.dataPoints.length; j++){
    	if(dataSeries.dataPoints[j].y <= 0)
      	dataSeries.dataPoints[j].color = 'rgb(170, 0, 0)';
    }
  }
}

Also, please take a look at this JSFiddle which shows setting different colors to positive and negative values.
