Why do we see certain colours even when they aren’t there? Chinese director Tang Han meticulously analyses the 100 Yuan bill, which carries a portrait of Mao Zedong, and finds that – despite official representations and general perception – the note is pink rather than red. In a serious tone and colourful, merry images she also casually upsets any number of other entrenched notions about digitalization, globalization, capitalism and gender.

An investigative examination of the colour spaces of the 100 Yuan note reveals a paradigm shift. Officially declared by the central bank to be red, the note bearing the portrait of Mao is, physically speaking, actually pink. This has consequences for China’s political narrative, as Tang Han’s uncompromisingly precise and refreshingly clever cinematic experimental setup illustrates.
