just an idea to develop a template dwg with preset layers and use as a template under the writer settings
Another option is to include DWGStyler in the output ports of an attribute filter set to the Color attribute in your translation. Template is the better approach.

I encountered the same thing and I ust tested this in FME 2015 and think it carries to 2016. Setting the color in the DWGStyler sets the individual entities, lines, blocks, etc, to that color. It does not set the color of the layer as shown in the Layer Properties Manager. First, I am assuming that you have multiple features writing to the DWG file. If you edit the properties of that feature writer, select the Format Parameters tab and there is a filed called Default Layer Color, which FME defaults to 10, which is red. The number here corresponds to the generic 255 color scheme in AutoCAD, so just type the number of the color you need. You can review this by editing the layer within AutoCAD and selecting a different color for the layer. That number should pop up in the color column within Layer Properties Manager. Hope this helps.

Sorry for the typos. I meant a field in the Format Parameters of any specific feature writer. You will need to change all features writers that you want to change the color from the default of red, 10.
