I have been able to change the color of point in a graph dynamically, but when I hover over that point then the color of that point is changing to previous color.

I have a fiddle here: jfiddle

$(function () {
var chart = new Highcharts.Chart({
    chart: {
        renderTo: 'container'
    },
    xAxis: {
        categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
    },

    series: [{
        data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]        
    }]
});

// the button handler
$('#button').click(function() {

    chart.series[0].data[2].graphic.attr({ fill: '#FF0000' });        
    chart.redraw();
});

How can I change the color of the point dynamically in a graph?

I think you are looking to update the marker color dynamically.

you can use update functionality for this

chart.series[0].data[0].update();

Here is a jsFiddle for your reference. I hope this will be useful for you.

is this what you are looking for?

http://jsfiddle/gh/get/jquery/1.7.1/highslide-software/highcharts./tree/master/samples/highcharts/plotoptions/series-marker-states-select-fillcolor/

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