Santa was first depicted wearing red, by cartoonist Thomas Nast in 1863, but up until the 1950's Santa was normally depicted wearing a green suit, sometimes also brown and white.
His suit changed to red after Coca-Cola started running an ad campaign. The artist Haddon Sundblom, who painted him for this ad, dressed him in red to match Coca-Cola's color scheme.
After a short time, this became the popular color for Santa's suit and is these days the norm.
