Colouring Piecharts created using JSChart

I create a piechart that has these results in tabular form.

Type    count

1 Pass 0 2 Failed 14 3 Uncovered 0

It has 3 sections, Pass, Failed, Uncovered. In the above example, Failed = 100% of the piechart. I would like to colour it so that Pass is green, Failed is pink and Uncovered is Red

I have tried two different code

<module name="HiddenChartFormatter">
                                   <param name="chart">pie</param>
                                  <param name="charting.fieldColors">{"Pass":0x009933,"Failed":0xff6ff2,"Uncovered":0xe00707}</param>

This does not work with JSChart.

<param name="charting.seriesColors">[0x009933, 0xff6ff2, 0xe00707]</param>

Using seriesColors does not tie a colour to a value, so in the above piechart, Failed would be green as it is the only field that shows up in the piechart.

Am I doing something wrong with fieldColors?
