Add several raster files (ecw) from one folder, Symbology RGB

Hello

I'd like to add several raster files (format: .ecw) from one folder with several subfolders to my mxd-file. It works fine with the following code:

workspace = r"C:\Workspace"   #Workspace
... 
... 
... #Code
... import arcpy, os
... 
... mxd = arcpy.mapping.MapDocument("CURRENT")
... df = arcpy.mapping.ListDataFrames(mxd, "*")[0]
... 
... walk = arcpy.da.Walk(workspace)
... 
... for dirpath, dirnames, filenames in walk:
...     for filename in filenames:
...         arcpy.mapping.AddLayer(df, arcpy.mapping.Layer(os.path.join(dirpath, filename)))

 

The Problem is, that after adding them like this, they appear with a symbology "stretched values along a color ramp" but they should be drawn as "RGB composite".

Can someone help me?
