highcharts: change color of pie slice on hover

highcharts: change color of pie slice on hover

when a slice of pie chart is hovered over i'd like it to change to the
designated hover color, and then change back to its original color once
the mouse is off that slice.
the documentation here
(http://api.highcharts.com/highcharts#plotOptions.series.marker.states.hover)
made it seem like the following would work, but i didn't have any luck:
http://jsfiddle.net/pixeloco/ztJkb/3/
plotOptions: {
series: {
marker: {
states: {
hover: {
fillColor: 'black'
}
}
}
}
},
i found this solution http://jsfiddle.net/r6p7E/6/, but it requires that
all slices be the same color. is there a way to have a multi-colored chart
with slices that change color on hover?
