I attached the sample code to create a Unique Value Renderer.  I also attached a sample Pro project that works in conjunction with the sample code.  The key code snippet is the creation of the unique value renderer: /// <summary> /// You must call this method on the MCT! /// </summary> /// <returns></returns> private CIMRenderer CreateUniqueValueRendererUsingColorTable(FeatureLayer lyrToColor, StandaloneTable colorTable) { //All of these methods have to be called on the MCT if (OnUIThread) throw new ArcGIS.Core.CalledOnWrongThreadException(); //make a dictionary with MapUnit and Color var dicMapUnitColor = new Dictionary<int, string>(); using (var rowCursor = colorTable.Search()) { while (rowCursor.MoveNext()) { using (var anyRow = rowCursor.Current) { dicMapUnitColor.Add((int)anyRow["MapUnit"], anyRow["Color"].ToString()); } } } //Create the Unique Value Renderer CIMUniqueValueRenderer uniqueValueRenderer = new CIMUniqueValueRenderer() { // set the value field Fields = new string[] { "MapUnit" } }; //Construct the list of UniqueValueClasses List<CIMUniqueValueClass> classes = new List<CIMUniqueValueClass>(); //define the unique values for each dicMapUnitColor entry foreach (var key in dicMapUnitColor.Keys) { var lstValue = new List<CIMUniqueValue>() { new CIMUniqueValue() { FieldValues = new string[] { key.ToString() } } }; var namedColor = System.Drawing.Color.FromName(dicMapUnitColor[key]); var theColor = CIMColor.CreateRGBColor(namedColor.R, namedColor.G, namedColor.B); classes.Add( new CIMUniqueValueClass() { Values = lstValue.ToArray(), Label = $@"Color: {dicMapUnitColor[key]}", Visible = true, Editable = true, Symbol = new CIMSymbolReference() { Symbol = SymbolFactory.Instance.ConstructPointSymbol( SymbolFactory.Instance.ConstructMarker(theColor, 20, SimpleMarkerStyle.Pushpin)) } } ); } //Add the classes to a group (by default there is only one group or "symbol level") // Unique value groups CIMUniqueValueGroup groupOne = new CIMUniqueValueGroup() { Heading = "By Color", Classes = classes.ToArray() }; uniqueValueRenderer.Groups = new CIMUniqueValueGroup[] { groupOne }; //Draw the rest with the default symbol uniqueValueRenderer.UseDefaultSymbol = true; uniqueValueRenderer.DefaultLabel = "All other values"; var defaultColor = CIMColor.CreateRGBColor(215, 215, 215); uniqueValueRenderer.DefaultSymbol = new CIMSymbolReference() { Symbol = SymbolFactory.Instance.ConstructPointSymbol( SymbolFactory.Instance.ConstructMarker(defaultColor, 15, SimpleMarkerStyle.Diamond)) }; return uniqueValueRenderer as CIMRenderer; }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Running the add-in using this input: and then changes the colors using the lookup: ...

You can use either the hostname, name, or the IsPortal flag (true if not AGOL) from PortalInfo: using this snippet: protected override async void OnClick() { try { var portal = ArcGISPortalManager.Current.GetActivePortal(); //Force login if (!portal.IsSignedOn()) { portal.SignIn(); } //If the sign in failed, this will be the default view of the portal var portalInfo = await portal.GetPortalInfoAsync(); MessageBox.Show($@"hostname: {portalInfo.PortalHostName} name: {portalInfo.PortalName} isportal: {portalInfo.IsPortal}"); } catch (Exception ex) { MessageBox.Show($@"Error: {ex}"); } }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...

Hi Douglas,  Actually there is a sample for attribute driven symbology here:  Renderer - AttributeDrivenSymbology.cs even so this sample shows rotation, however, if you don't have a sample for your rendering needs, you can follow the approach outlined here:   I use the CIMViewer to take a look at a symbol that is using attribute values for its color.  The CIMViewer add-in allows you to look at the cartographic information model for each CIMFeatureLayer, which in turn contains the CIMRenderer definition.  I changed my layer's symbology through the Pro UI to use an attribute driven color and looking at the CIMViewer's XML output, I found that my CIMSimpleRenderer had been modified as shown below in order to support the coloring by attribute value (you can see the XML of the CIM Renderer).  Also a matching 'PrimitiveName' reference was added to the symbol layer that needed the color replaced (not shown here): <Renderer xsi:type="typens:CIMSimpleRenderer"> <Patch>Default</Patch> <Symbol xsi:type="typens:CIMSymbolReference"> <PrimitiveOverrides xsi:type="typens:ArrayOfCIMPrimitiveOverride"> <CIMPrimitiveOverride xsi:type="typens:CIMPrimitiveOverride"> <PrimitiveName>d704d106-8f6f-4ef4-8ee9-3e8c4c7a2c8c</PrimitiveName> <PropertyName>FillColor</PropertyName> <Expression /> <ValueExpressionInfo xsi:type="typens:CIMExpressionInfo"> <Expression>$feature.Color</Expression> <ReturnType>Default</ReturnType> </ValueExpressionInfo> </CIMPrimitiveOverride> </PrimitiveOverrides> <Symbol xsi:type="typens:CIMPointSymbol"> .......‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ <SymbolLayers xsi:type="typens:ArrayOfCIMSymbolLayer"> <CIMSymbolLayer xsi:type="typens:CIMVectorMarker"> ... <MarkerGraphics xsi:type="typens:ArrayOfCIMMarkerGraphic"> <CIMMarkerGraphic xsi:type="typens:CIMMarkerGraphic"> <PrimitiveName>d704d106-8f6f-4ef4-8ee9-3e8c4c7a2c8c</PrimitiveName> </CIMMarkerGraphic> </MarkerGraphics> ... </CIMSymbolLayer>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ If you look at the sample referenced above using the CIMView's XML output, you can come up with a snippet like the one below that changes the color using the text field "TestPoints.Color", which contains values like 'Red', 'Green', 'Blue'.  Note that the 'PrimitiveName' in the primitive override has to match the one in the CIMMarkerGraphics. protected override void OnClick() { var lyr = MapView.Active.Map.GetLayersAsFlattenedList().OfType<FeatureLayer>().Where(f => f.Name == "TestPoints").FirstOrDefault(); if (lyr == null) return; QueuedTask.Run(() => { //Get the layer's renderer var renderer = lyr.GetRenderer() as CIMSimpleRenderer; var primitiveName = Guid.NewGuid().ToString(); var cimPO = new CIMPrimitiveOverride() { PrimitiveName = primitiveName, PropertyName = @"FillColor", Expression = null, ValueExpressionInfo = new CIMExpressionInfo() { Expression = @"$feature.Color", ReturnType = ExpressionReturnType.Default } }; (renderer.Symbol.Symbol as CIMPointSymbol).SymbolLayers[0].PrimitiveName = primitiveName; var overrideList = new CIMPrimitiveOverride[1]; overrideList[0] = cimPO; //Apply symbol overrides renderer.Symbol.PrimitiveOverrides = overrideList; //Apply the renderer to the feature layer lyr.SetRenderer(renderer); }); }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...
