General Mills introduced Trix in 1954 as a sugar-coated version of its popular
Kix cereal. The original Trix cereal was composed of more than 46% sugar and included three colors: "Orangey Orange" (formerly named Orange Orange), "Lemony Yellow" (formerly named Lemon Yellow), and "Raspberry Red". Five fruit shapes and colors were added over the years: "Grapity (or Grapey) Purple" (1984–present), "Lime Green" (1991–1998, 2007–2015, 2017–present), "Wildberry Blue" (1997–2007, 2018–present), "Berry Blue" (2007–2015, 2017–present), and "Watermelon" (1998–2007, 2018–present). In 1991 and again in 1995, the cereal pieces were given a brighter, more colorful look. General Mills'
Yoplait division produces a Trix-branded
yogurt marketed to children with sweetened fruit flavors such as "Watermelon Burst". Later, Trix Swirls were introduced, with flavors such as "Rasp-orangey orange swirl" (a mix of the Orangey orange and Raspberry red flavors). A new flavor, "Wildberry Red Swirl", was introduced in 2011. Trix Swirls have since been discontinued, and the pieces in the original Trix were changed to their original 2007 flavor and shape lineup in 2014. The cereal originally used spherical cereal pieces, but in 1991 these were changed to puffed fruit-shaped pieces, presumably to avoid clashing with
Berry Berry Kix when it was introduced in 1992. In 2007, Trix reverted to their original shapes in the United States, much to fans' dismay. Mexico was the only country to maintain fruit-shaped pieces until around late 2018, when they were reintroduced globally. In 2015, General Mills announced it would no longer use
artificial colors in its cereals, and Trix would be among the first to change. Trix would go from six colors to four because satisfactory natural alternatives were found for orange, yellow, red, and purple, but not blue or green. On September 21, 2017, General Mills announced that the six-color version of Trix cereal would be reintroduced back to the market, and that artificial dyes and flavors would be utilized to do so after customers complained about the naturally-flavored Trix. The four-color, non-artificial-dye/flavor version would continue to be sold. In that same announcement, General Mills said they would revert to the puffed fruit-shaped pieces, which happened around late 2018. ==Marketing and advertising==
