LITCherry-blossom pink comes from small amounts of anthocyanin in the petals. Many popular varieties (such as Somei-yoshino) open very pale pink and fade toward white. Anthocyanins absorb green, around 500–560 nm depending on pH and co-pigments.

MODELAn absorption band centred at 530 nm (my shape) scaled by anthocyanin over a white petal, through CIE with Bradford. Days after opening fade the pigment (a toy decay). Tap for wind. Nesting: a white petal core, pink in the canopy, void.
