Usage
For a pie chart, ColdFusion sets pie slice colors as follows:
• If the seriesColor attribute is omitted, ColdFusion automatically determines the colors of
the slices.
• If the seriesColor attribute is specified, ColdFusion automatically determines the colors of
the slices after the first one, starting with the specified color for the first slice.
