Which Coca-Cola soft drink was introduced in 1979 with a citrus flavor?

Mello Yello was introduced by Coca-Cola in 1979 as a citrus-flavored soft drink.

Coca-Cola launched Mello Yello in the United States to compete in the growing citrus-soda category. Its flavor profile and bright yellow branding were designed to give the drink a youthful, energetic identity.

The brand name uses a stylized spelling of “mellow yellow.” Its advertising emphasized an active, adventurous image, helping distinguish it from Coca-Cola’s cola beverages and from other citrus sodas.

Mello Yello is sometimes mixed up with Fresca, which Coca-Cola introduced earlier as a grapefruit-flavored soft drink, and with Surge, a later citrus beverage. Mello Yello’s original national introduction dates to 1979, although its distribution and product variations have changed over time.
