Colorramp in arcgis wpf ???

Question

I have a properties dialog that let user select a theme color and based on the theme that I generate colors which will be applied to different regions of a map.

Before, we use arcgis 9.3 api, there are ESRI.ArcGIS.Display.IEnumColors class that can generate colors for us.  Now, we are using arcgis wpf apis only, is there a similar class that achieve the same work?

Code example of what we did:

IColorRamp colorRamp = ColorRampInstance;
colorRamp.Size = 5
bool ok = true;
colorRamp.CreateRamp(out ok);

IEnumColors enumRamp = colorRamp.Colors;
IColor nextUniqueColor = enumRamp.Next();

How can we achieve the same thing using arcgis wpf apis?

Thanks!

Ah I see. You can refer to this SDK sample: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#Thematic_Interactive.

This other sample use ClassBreaksRenderer: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#FeatureLayerRendering

The first example is not quite what I'm looking for either because it uses only 1 basic color while I have 3.
I just want to know if arcgis wpf provides a quick way like arcgis desktop api does.
Thanks for your effort!

Attached is a map with different colors applied to different regions.  These colors are generated by IColorRamp based on the theme colors I pass in.  Hope this helps.
