Researchers have discovered and recently presented five types of penicillium that are bright orange, reminding them of the main colour of the Dutch Royal family, aka the House of Orange-Nassau.

They call them ‘Penicillium vanoranjei’ (family) and fourth other kinds that belong to this family, named after Crown-Prince Willem-Alexander’s three daughters (Amalia, Alexia and Ariane) and wife and future Queen consort Máxima: Penicillium maximae, Penicillium amaliae, Penicillium alexiae and Penicillium arianeae.
