The London Financial Times newspaper is printed on pink paper, according to an article on alder, Alnus glutinosa in ‘Richmond Park Diary – January 2022’, displayed on information-boards at the entrances to the Park:

‘The timber [of alder] is white when first felled but soons turns pink-orange.  It is reputed that low-grade paper made from alder was used to print the Financial Times in 1893,  whether this was a deliberate or accidental marketing exercise to distinguish the paper from its rival [sic.] is uncertain, but nowadays the paper retains its colour.’
