 Between the 1970-71 and 2002-03 seasons, NHL teams wore white (or yellow) uniforms at home and dark uniforms on the road (which is the current convention in some low-level ice hockey leagues).Since the 2003–04 season, NHL teams typically wear the dark color at home and the white for road games; there are occasional single-game exceptions.The only element allowed by NHL rules to be interchangeable between the two sets of equipment is the pants.
