Rainbow S.p.A. is an Italian studio founded by Iginio Straffi and co-owned by Viacom (later Paramount Global) from 2011 to 2023.

Rainbow began as an animation studio, providing creative services for larger companies until it secured enough funds for original productions.

[7] In 2017, Rainbow acquired a majority stake in Gruppo Iven S.p.A., which owns the production company Colorado Film.

[10] According to Straffi, this presented "a real dilemma" as Viacom was already listed on an American stock exchange,[10] but Rainbow performed best in European countries.

While Nickelodeon will continue to be a broadcast partner for the studio, the purchase allows Straffi full control of Rainbow's new projects.
