I'm looking for a way to automatically assign a color to a feature, mainly polylines. I want to do this by populating a field with a value so I can link it to a color. I believe this is possible with representation symbology, but I haven't been able to find out how to use the override field for color. Is there a specific type of field it has to be? Is there some format the attributes have to be, ie RGB values? Perhaps there are other ways to do this as well? I am open to ideas, but representation symbology is what I need the end result to be.
