Skittles candy products, produced by the Wm. Wrigley Jr. Company, come in a wide variety. Most of the varieties are available only in particular regions of the world. The oldest Skittles product is Original Fruit Skittles, which was originally released in Europe in 1974, and was launched in the United States in 1979. The most recent flavor, Sweet Heat, was released in 2018. Earlier Skittles products tended to focus on fruit flavors, more recent products have branched out to include flavors such as chocolate, bubble gum, popcorn, mint, and sours. Skittles products also come in a wide variety of colors, although different Skittles products often use the same colors for sweets with different flavors. For example, the color yellow is associated with lemon flavor in Original Fruit Skittles and as banana berry in Tropical Skittles.
