    Hello,

    The 9th color is the same like the first one because the chart's theme has 8 different colors and when you have more than 8 slices in the pie the colors start repeating again from the first one. You can provide a different color by implementing chart:paletteItemForSeries:atIndex method of TKChartDelegate. Using the index you can return a palette item with a different color for the corresponding slice. Consider the code below:
    - (TKChartPaletteItem *)chart:(TKChart *)chart paletteItemForSeries:(TKChartSeries *)series atIndex:(NSInteger)index {
        if (index == 1) {
            return [TKChartPaletteItem paletteItemWithFill:[TKSolidFill solidFillWithColor:[UIColor redColor]]];
        }
         
        return nil;
    }
