Answer: Red

If you’re looking for the most patriotic color on Earth (per its use in national flags around the globe), then the color you’re looking for is red—in all its vermilion glory.

While the most prolific color, in terms of a single pure shade and due to how often it is used for detailing in crests and such is pure white (appearing in 17.7 percent of flags), the most frequently used color when you factor in the various shades of it is red.

Some shade of red appears on over 25 percent of the world’s national flags, ranging from the very bold and obviously red flags like those of Canada and Denmark to the more subtle use of red in flags like those of Uzbekistan and Belize.
