We have ChartColorPalette property of charts to set different color palettes. If you do not want to specify custom colors for palette, at that time you can use following specified palettes.
The ChartColorPalette represents the palettes to be used for the root Chart object and any Series objects. If no colors are assigned to data points and their associated series, the default colors will be assigned to the data
