As a relatively inexpensive and readily-available paint colour, and one which went well alongside the near-universal black hull and white superstructure used on steamships at the time, White Star was far from the only shipping line to use a shade of buff as a funnel colour. The Orient Line and Norddeutscher Lloyd used an entirely buff funnel without the black top, while Canadian Pacific and the Swedish American Line employed a buff funnel with a representation of the company's house flag on them."
