Reason 1: A Fill Pattern is Necessary

Besides setting the ForeColorRGBA property, it may also be necessary to set the object's fill pattern, such as:

Polygon.Fill.Pattern = "Diagonal Cross"
Polygon.Fill.Transparent = True
Polygon.Fill.ForeColorRGBA.Color = srfColorOrange

Reason 2: Fill the Contours

If you are setting the fill color of a contour map, be sure you set FillContours to True before setting the fill colors:

ContourLayer.FillContours = True
ContourLayer.FillForegroundColorMap.LoadPreset("Rainbow")

Reason 3: Apply the Fill to the Contours

After changing the colormap for a contour layer (e.g. loading a CLR file or specifying a preset), you need to apply the fill changes.

ContourLayer.FillForegroundColorMap.LoadPreset("Rainbow5")
ContourLayer.ApplyFillToLevels(FirstIndex:=1, NumberToSet:=1, NumberToSkip:=0)

If that does not help, please email a small sample script that can be run in Scripter that shows the problem, and a description of what you are trying to do, to surfersupport@goldensoftware.com.
