Fun fact about Santa: He's only worn red since he started shilling for Coca-Cola.
Santa's had a wide range of colorful outfits over the years—green, brown, blue, and even tan—but it's only been since 1931 that he's known to wear primarily a red-and-white suit. It's all thanks to the Coca-Cola company, which used Santa in the early 30s to sell Coke products, and of course dressed him in the brand's trademark colors. It's been that way ever since, and Santa continues to be one of the centerpiece of Coke's holiday advertising campaign.
