Summary

[edit]
Description
English: Ranunculus acris (Meadow buttercup) flower photographed in visible light (left), ultraviolet (middle), and infrared (right).

In visible light the flower has glossy bright yellow petals, with the base of the petals being slightly less saturated in colour. At the centre of the flower is a cluster of bright green - yellow coloured pistils. The gynoecium is surrounded by bright yellow coloured stamens. In terms of tone the sexual parts of the flower and the petals are roughly the same tone.

In ultraviolet the petals appear less glossy. At the base they have dark ultraviolet markings, matching the areas of the petals that appear slightly less brilliant yellow in visible light. The gynoecium and stamens appear very dark in ultraviolet.

In infrared the flower appears less glossy than it does in visible light, though glossier than in ultraviolet. All parts of the flower appear roughly the same tone, as in visible light.
