Color each bar individually in a grouped, stacked bar chart in jfreechart

In jfreechart, I have a renderer such as

GroupedStackedBarRenderer renderer = new GroupedStackedBarRenderer();

I my example I have 4 groups of 5 stacked bars (2 bars each stack), all in all 40 bars.

I have used a construction like

renderer.setSeriesPaint(0 + 2 * (length * s + g), <color for this bar>);
renderer.setSeriesPaint(1 + 2 * (length * s + g), <color for this bar>);

in order to color each bar individually, where g denotes the group, 'length' is the number of groups, s the stacked bar number within the group.

Unfortunately this does not work. What am I doing wrong?

You should be able to create any color scheme you want by overriding getItemPaint(), as shown in this example. Note the use of StandardXYBarPainter. It may help to print out a few values, as shown here. If not, please edit your question to include an sscce that shows your approach.
