Changing default colours of CPTPieChart

In CorePlot if you create a CPTPieChart object the default colours for the data slices seem to be green, red, blue.

How can I change them? Here is a code snippet I am using to create the graph..

pieChartGraph = [[CPTXYGraph alloc] initWithFrame:self.pieChartgraphHostView.bounds];
peChart.dataSource = self;
//... code 
// pieChart addSublayer:

self.dataForChart = [@[@25.0, @25.0, @48.0, @2.0] mutableCopy];

Implement one of the following datasource methods:

-(nullable CPTFill *)sliceFillForPieChart:(nonnull CPTPieChart *)pieChart recordIndex:(NSUInteger)idx;
-(nullable NSArray *)sliceFillsForPieChart:(nonnull CPTPieChart *)pieChart recordIndexRange:(NSRange)indexRange;

Provide the fill for the slice with the given index. If the datasource returns nil, the default fill is used. If the datasource returns an NSNull object, no fill is drawn for the slice at that index.
