Hi,our offside (driver) bump strip departed our company on the motorway,meeting a sticky end with a wagon

I'm trying to buy a replacement from some bloke but he wants to know if I need dark silver or graphite.He says himself there's not much difference in the colour,but I don't want to fork out money for the wrong one.Whats the official opinion on the matter?We have a 2004 dynamique which is blue.Please help this female
