Hello CW,

Please check the approach in our Clustering Help Artcile. You can use the ClusterItemTemplate property of the VisualizationLayer and add Ellipse in a DataTemplate. You can bind the Background / Fill of the Ellipse or other element in the Template to the Count property of the underlying ClusterData object. Converter will help you to set different background / fill depending on the Count. 

<DataTemplate x:Key="ClusterTemplate">
    <Border Background="#af3f3f3f"
            CornerRadius="3"
            MouseLeftButtonDown="ExpandClusterToPolygon"
            MouseRightButtonDown="ExpandCluster"
            telerik:MapLayer.HotSpot="0.5,0.5">
        <Ellipse Fill={Binding Count, Converter ={StaticResource />
    </Border>
</DataTemplate>
