Hanna-Barbera Studios Europe

Background
Hanna-Barbera Studios Europe (formerly Cartoon Network Development Studio Europe and Cartoon Network Studios Europe) is the European division of Cartoon Network Studios, which is based in London. It was founded in 2007. On April 7, 2021, the studio changed its name to their current name, which is a homage to Hanna-Barbera.

Logo (December 5, 2022-)
Visuals: On a black background, a rounded and bubbly "HB", styled after the 1974 classic "Rainbow" Hanna-Barbera logo (as well as the short-lived 2017 revival unit of Warner Bros. Animation) and in a blend of pastel //yellow shades, swirls around the screen while leaving a solid trail behind it and zooming in. As it reaches the center of the screen, the text "HANNA-BARBERA STUDIOS EUROPE" in a white Microgramma font appears below. Copyright information is seen during this.

Trivia: This logo is a homage to Hanna-Barbera's 1979 "Rainbow" and 1986 "Swirling Star" logos.

Variant: A version without any copyright information below exists.

Technique: 2D computer animation.

Audio: An uprising flute with a series of ascending chimes, finishing off with a synth flourish. This was arranged by Xav Clarke.

Availability: It can currently be seen on international airings of The Heroic Quest of the Valiant Prince Ivandoe full series (beginning from December 2022), and will also likely appear on upcoming projects from the company.
