If you are using a CategoryPlot to draw the chart, then you can use setSeries() method of the CategoryItemRenderer class. It will allow you define colors for each different series., hence making the bars look different.

Finally got the thing done by extending the default bar renderer class and assigning specific colors to specific bars
