Create and initialize the DashboardPalette class instance and assign the resulting object to the e.Palette event parameter:
using DevExpress.DashboardCommon;
using DevExpress.DashboardWeb;
using System.Collections.Generic;
using System.Drawing;
// ...
protected void ASPxDashboard1_CustomPalette(object sender, CustomPaletteWebEventArgs e) {
// Create a new custom palette.
List<Color> customColors = new List<Color>();
customColors.Add(Color.LightBlue);
customColors.Add(Color.Aquamarine);
customColors.Add(Color.SkyBlue);
customColors.Add(Color.LightCoral);
customColors.Add(Color.Tomato);
customColors.Add(Color.IndianRed);
customColors.Add(Color.Violet);
customColors.Add(Color.Plum);
customColors.Add(Color.MediumOrchid);
// Assign a newly created custom palette to the Web Dashboard.
e.Palette = new DashboardPalette(customColors);
