Summary edit

Description
English: Comparison of Jacobaea maritima (Silver Ragwort) flowers photographed with visible light (top), ultraviolet light (middle), and infrared light (bottom).

In visible light the flowers appear bright yellow, with the centres being slightly darker than the petals.

In ultraviolet light the centres appear quite dark, helping guide bees and other insects that can see in the ultraviolet spectrum to the area of the flower where the nectar and pollen are located.

In infrared light the petals and centres of the flowers have roughly the same reflectance.
