Why must the first footer in hogmanay dark haired?

In Scottish tradition, particularly during Hogmanay, the first footer—someone who is the first to enter a home after midnight—is ideally dark-haired as it symbolizes good luck and prosperity for the coming year. The belief stems from the idea that a dark-haired person represents strength and stability, in contrast to a light-haired individual who might symbolize the opposite. This custom is deeply rooted in folklore and is part of the broader celebratory practices surrounding the New Year in Scotland. The first footer often brings gifts, such as coal or bread, to ensure good fortune for the household.
