Change colors in devexpress charts - asp.net-mvc

Question

I am drawing a pie chart using Devexpress in my MVC project.
While doing it by default my chart generated with three colors, as below
but my client is not satisfied, with the colors of it and wanted me to change them which match with our application background, so please help me, how to do this.
Thanks in advance.
Here is my code.
settings.Name = "chart";
settings.Width = 600;
settings.Height = 250;
settings.BorderOptions.Visible = false;
Series series1 = new Series("Type", DevExpress.XtraCharts.ViewType.Pie3D);
settings.Series.Add(series1);
series1.ArgumentScaleType = ScaleType.Qualitative;
series1.ArgumentDataMember = "ClassName";
series1.ValueScaleType = ScaleType.Numerical;
series1.ValueDataMembers.AddRange(new string[] { "PercentageValues" });
series1.LegendPointOptions.PointView = PointView.ArgumentAndValues;
series1.LegendPointOptions.ValueNumericOptions.Format = NumericFormat.Percent;
series1.LegendPointOptions.ValueNumericOptions.Precision = 0;
series1.Label.ResolveOverlappingMode = ResolveOverlappingMode.Default;
series1.Label.Visible = false;

Answer 1

Please refer the following code. I have successfully implemented the same for giving custom color for rangebar. I guess it will work for your case also
settings.CustomDrawSeriesPoint = (s, ev) =>
{
BarDrawOptions drawOptions = ev.SeriesDrawOptions as BarDrawOptions;
if (drawOptions == null)
return;
Color colorInTarget = Color.Blue;
double x = ev.SeriesPoint.Values[0];
double y = ev.SeriesPoint.Values[1];
if (x == 0)
{ //Do starting
colorInTarget = Color.FromArgb(159,125, 189);
}
else{
//Red - price Increase
// Green price Decrease
if (y > previousYValue)
{
colorInTarget = Color.Red; ;
}
else
{
colorInTarget = Color.Green;
}
}
previousYValue = y;
drawOptions.Color = colorInTarget;
drawOptions.FillStyle.FillMode = FillMode.Solid;
drawOptions.Border.Color = Color.Transparent;
};

Answer 2

you can set the theme and palette properties of the chart control. follow the links below to devexpress documentation. although the examples refers to winform application they are still avaliable in asp.net mvc controls.
http://documentation.devexpress.com/#WindowsForms/CustomDocument7433
http://documentation.devexpress.com/#WindowsForms/CustomDocument5538
// Define the chart's appearance and palette.
barChart.AppearanceName = "Dark";
barChart.PaletteName = "Opulent";
