Taco Bell is so old that, while it's not ancient in terms of the world's age, the world has changed so much since 1962 that if we were to describe the intervening years as 600 years rather than 60, we wouldn't be doing it an injustice.
Taco Bell stands out from its competitors not only by selling tacos, but also by choosing a color palette consisting of purple tones rather than red tones.
