when did father christmas change from green to red

The modern image of Santa Claus or Father Christmas as a jolly, plump, and bearded man in a red suit is a relatively recent development. The original depiction of Santa Claus was as a tall, gaunt, and stern figure who dressed in green. The shift to the red and white color scheme and the chubby, cheerful appearance we recognize today is believed to have been popularized by Coca-Cola in the 1930s. The company used the image of a jolly, rosy-cheeked Santa in its advertising campaigns, and the red-and-white color scheme became closely associated with the character.
