Change the Lines Style and colour of a JFreeChart

I have 3 series:

XYSeries s1 = new XYSeries("one");
s1.add(1,0);
s1.add(2,1);

XYSeries s2 = new XYSeries("two");
s1.add(3,0);
s1.add(4,1);

XYSeries s3 = new XYSeries("three");
s1.add(5,0);
s1.add(6,1);

Which i plot as a XYLineChart:

XYSeriesCollection dataset = new XYSeriesCollection();
dataset.addSeries(s1);
dataset.addSeries(s2);
dataset.addSeries(s3);

JFreeChart chart = ChartFactory.createXYLineChart("title", "x", "y", dataset, PlotOrientation.VERTICAL, false, false, false);

and add to a panel:

ChartPanel cp = new ChartPanel(chart);
panel_1.add(cp, BorderLayout.CENTER);
panel_1.validate();

How do i make it so series s1 and s2 are the same colour, and s3 is different?

You can use the renderer's setSeriesPaint() method to specify the series and paint. Also consider using a custom DrawingSupplier, mentioned here. More generally, you can override the desired get*Paint() methods to establish any desired color scheme, as shown here for getItemFillPaint()
