How to i set jqplot bar chart colours per bar?

Question

I'm trying to set the colours of my jqplot bar chart bars. There will always be six bars present, grouped into sets of 2 bars. Here is an example of the data being plotted:

 line1 = [6000, 5000, 5500];
 line2 = [16000, 10000, 14000];

I've used the following so far:

 seriesColors: ["#F3CBBF", "#BFDDE5", "#CF3501", "#027997", "#CF3501", "#027997"],

But jqplot alternates between the first 2 bars each time instead of using all of the declared colours. This is probably as it only determines 2 series being present, one per set of data.

Is there a way to set the bar colours explicitly?

I do this using the varyBarColor method so you can list the different colours for the bars in a simple array like you have done already but if there is only one series it will use these colors for each bar instead. Here is an example of my code:

plot1 = $.jqplot('chart1', [s1], {
        title: 'Example Income Graph',
        seriesDefaults:{
            renderer:$.jqplot.BarRenderer,
            rendererOptions:{ varyBarColor : true },
            pointLabels: { show : true }
        },
        axes: {
            xaxis: {
                renderer: $.jqplot.CategoryAxisRenderer,
                label:'Net Growth (%)',
                ticks: ticks
            },
            yaxis:{
              label:'Income (£)',
              tickOptions:{ formatString:'%d'},
              autoscale:true,
              min:0, 
              max:10000
            }
        },
        seriesColors: [ "#eee", "#ccc", "#999"],
        highlighter: { show: false }
    });

In this graph I had one series with 3 bars and they are each a different colour grey.
