Remarks

The following code shows how to configure a treemap colorizer that uses a newly created palette, and specify the palette scale mode:

C#

using DevExpress.XtraTreeMap;
using System.Drawing;
//...
    Palette palette = new Palette();
    palette.AddRange(new Color[] {
        Color.FromArgb(255, 153, 203, 56),
        Color.FromArgb(255, 99, 165, 55),
        Color.FromArgb(255, 55, 167, 111),
        Color.FromArgb(255, 68, 193, 163),
        Color.FromArgb(255, 78, 179, 207),
        Color.FromArgb(255, 81, 195, 249),
    });
    palette.ScaleMode = PaletteScaleMode.Repeat;

    TreeMapPaletteColorizer colorizer = new TreeMapPaletteColorizer() { Palette = palette, ColorizeGroups = true };
    treeMapControl1.Colorizer = colorizer;

VB.NET

Imports DevExpress.XtraTreeMap
'...
    Dim palette As Palette = New Palette()
    palette.AddRange(New Color() {
        Color.FromArgb(255, 153, 203, 56), 
        Color.FromArgb(255, 99, 165, 55), 
        Color.FromArgb(255, 55, 167, 111), 
        Color.FromArgb(255, 68, 193, 163), 
        Color.FromArgb(255, 78, 179, 207), 
        Color.FromArgb(255, 81, 195, 249)
    })
    palette.ScaleMode = PaletteScaleMode.Repeat
    Dim colorizer As TreeMapPaletteColorizer = New TreeMapPaletteColorizer() With {
        palette,
        .ColorizeGroups = True
    }
    treeMapControl1.Colorizer = colorizer
