Based on the world record nomination from Euroupe Records Institute (EURI) and Decision No. WK/USA.INDIA/771/2021/No.227, World Records Union (WorldKings) officially declared Allianz Arena as the World’s first stadium with a full colour changing exterior on November 11th, 2021

Allianz Arena is a football stadium in Munich, Bavaria, Germany with a 70,000 seating capacity for international matches and 75,000 for domestic matches. Widely known for its exterior of inflated ETFE plastic panels, it is the first stadium in the world with a full colour changing exterior. Located at 25 Werner-Heisenberg-Allee at the northern edge of Munich's Schwabing-Freimann borough on the Fröttmaning Heath, it is the second-largest arena in Germany behind Westfalenstadion in Dortmund.

The stadium construction began on 21 October 2002 and was officially opened on 30 May 2005. The primary designers are architects Herzog & de Meuron. The stadium is designed so that the main entrance to the stadium would be from an elevated esplanade separated from the parking space consisting of Europe's biggest underground car park.

The roof of the stadium has built-in roller blinds which may be drawn back and forth during games to provide protection from the sun.

The arena facade is constructed of 2,874 ETFE-foil air panels that are kept inflated with dry air to a differential pressure of 3.5 Pa.

The panels appear white from far away but when examined closely, there are little dots on the panels. When viewed from far away, the eye combines the dots and sees white. When viewed close up however, it is possible to see through the foil. The foil has a thickness of 0.2 mm. Each panel can be independently lit with white, red, or blue light.

The panels are lit for each game with the colours of the respective home team—red for Bayern Munich, blue for TSV and white for the German national football team. White is also used when the stadium is a neutral venue, like the 2012 UEFA Champions League Final.

Other colours or multicolour or interchanging lighting schemes are theoretically possible, but the Munich Police strongly insists on using a single-colour lighting scheme due to several car accidents on the nearby A9 Autobahn with drivers being distracted by the changing lights.

Allianz Arena's innovative stadium-facade lighting concept has been subsequently adopted in other recently built venues, like MetLife Stadium in New Jersey, which lights up in blue for the National Football League's Giants and green for the Jets. With electricity costs for the light of about €50 (USD$75) per hour, the construction emits enough light that, on clear nights, the stadium can easily be spotted from Austrian mountain tops, e.g. from a distance of 50 miles (80 km).
