Janene,

Welcome&nbsp;you&nbsp;to&nbsp;ThinkGeo&nbsp;Map&nbsp;Suite&nbsp;Desktop&nbsp;Forum!  
&nbsp;  
I&nbsp;think&nbsp;you&nbsp;Gradient&nbsp;Style&nbsp;is&nbsp;exactly&nbsp;what&nbsp;you&nbsp;are&nbsp;trying&nbsp;to&nbsp;find,&nbsp;following&nbsp;is&nbsp;some&nbsp;snippet&nbsp;of&nbsp;codes&nbsp;you&nbsp;can&nbsp;take&nbsp;reference&nbsp;when&nbsp;using&nbsp;the&nbsp;Gradient&nbsp;Style.  
`ShapeFileFeatureLayer worldLayer = new ShapeFileFeatureLayer(@"..\..\SampleData\Data\Countries02.shp");worldLayer.ZoomLevelSet.ZoomLevel01.CustomStyles.Add(AreaStyles.Country1);worldLayer.ZoomLevelSet.ZoomLevel01.ApplyUntilZoomLevel = ApplyUntilZoomLevel.Level20;GradientStyle gradientStyle = new GradientStyle("POP_CNTRY", 0, new GeoSolidBrush(GeoColor.SimpleColors.Green), 2000000000, new GeoSolidBrush(GeoColor.SimpleColors.Red));gradientStyle.RequiredColumnNames.Add("POP_CNTRY");worldLayer.ZoomLevelSet.ZoomLevel01.CustomStyles.Add(gradientStyle);`

Also,&nbsp;if&nbsp;you&nbsp;want,&nbsp;you&nbsp;also&nbsp;can&nbsp;try&nbsp;to&nbsp;use&nbsp;the&nbsp;ClassBreakStyle&nbsp;or&nbsp;ValueStyle&nbsp;to&nbsp;achieve&nbsp;your&nbsp;requirement,&nbsp;please&nbsp;take&nbsp;a&nbsp;look&nbsp;at&nbsp;the&nbsp;following&nbsp;HowDoI&nbsp;samples:

Styles\Draw&nbsp;features&nbsp;based&nbsp;on&nbsp;values  
Styles\Draw&nbsp;thematic&nbsp;features  
&nbsp;  
Let&nbsp;me&nbsp;know&nbsp;if&nbsp;you&nbsp;have&nbsp;any&nbsp;other&nbsp;questions.  
&nbsp;  
Thanks.
