Rainbow High made its debut in 2020. Rainbow High is a doll line, and the first piece of merchandise for the Rainbow Highfranchise. At its core, Rainbow High is best represented by the dolls they produce of which are the promoted by the animated series. Each doll comes with an extra outfit, including shoes, a stand, hangers, and a comb to brush the doll’s hair. The dolls are usually monochromatic to a specific color (which is occasionally left vague), though some dolls tend to derive from the color and include different colors in the outfit.

A web series of animated shorts was announced [3] following the release of the first dolls. The series is produced by Australian animation studio Pixel Zoo[4] with the financial backing from the Screen Queensland initiative of the Queensland Government with the first episode premiering on October 2, 2020, and additional episodes released at least every fortnight. The web series was complemented with spin-offs premiering every other week; looking at the activities and adventures of Rainbow High in the eyes of Violet Willow with her show, "The Vi Life" (pronounced "vie life"), and Karma Nichols with her show, "Kontent with Karma" with the latter debuting on 16 April 2021.

The web series concluded its first season on 11 June 2021[5] The second season premiered on 16 July 2021 and concluded on 28 January 2022, with the third season featuring the rival school, "Shadow High", beginning 2 months later on 25 March, and concluded 23 November of that same year. The fourth season premiered on 8 June, 2023[6] and concluded on 24 November of that same year, ending on a cliffhanger. The fifth season premiered with three episodes on 22 March 2024 and concluded on 6 September of the same yearThe sixth season premiered on March 14, 2025, the 7th Season has been released in 2026

Following their release in mid-2020, the doll franchise appeared on multiple hot-toy lists including Toys "R" Us Canadaand The Toy Insider,while The NPD Group reported in August 2020 that, Rainbow High was the No. 3 best selling fashion doll line and the No. 7 best selling doll line overall in the U.S.
 

Unlike most lines, the core dolls are split into a different series. There are usually two series per year, including around 6 new characters per series, although sometimes stand-alone dolls are released, usually labeled Special Edition or Collector Edition.

The dolls' bodies were changed after Series 2 to include better mobility with the heads, allowing them to rotate and move up and down.

The dolls used to have the same face mold, but after Series 3, a new milestone was reached with the introduction of more new face molds for the dolls.

In 2024, a soft reboot was made to the line, featuring slime gimmicks and the removal of wrist articulation.

in 2026, they may end up being reitred
