I see he probably did get this wrong. A cartoonist invented red Santa in 1863 for Harper's Weekly and Coca-Cola used red Santa in 1938. - From the comments.

I suppose both stories could be true. I think I'll Google an image of the 1863 Santa. But why a red Santa at that time?

I like him wearing green. It's my favorite color.

Edit-

"In 1863, Santa Claus did not wear his signature red suit in Harper's Weekly, as the magazine was printed entirely in black-and-white wood engravings. While cartoonist Thomas Nast famously introduced the prototype of our modern Santa Claus on the January 3, 1863 cover of Harper's Weekly, the actual text accompanying the illustration reveals that Santa was dressed in a patriotic Union uniform of a star-covered jacket and striped trousers rather than a solid color.Nast did not popularize the iconic bright red outfit until 1881, when his famous colorized illustration titled "Merry Old Santa Claus" was published.

Thank you, AI

Edit 2- He was wrong. He should stick to his area of expertise.
