Usually at local kickoffs (if this is your first local kickoff that you attended) they use the cheaper costing parts to make up a partial segment of the field since FIRST has not built enough fields for each local kickoff event. Not to mention not all events have the space to have a nice looking Field Layout. Which would explain why the metal was dull. The Metal will probably have a clean aluminum color to it for at least a few rounds before being scratched up by the robots. Why don't you try using the camera supplied in the kit and search for the Green Lights. Instead of looking for metal, since a large portion of the field is metal (Barriers, Walls & Goals - They mostly have the same color as well).
