Summary

[edit]
Description
English: Comparison of a Orange Hawkweed (Pilosella aurantiaca) flower in visible light (top), ultraviolet light (centre), and infrared light (bottom).

The flower appears slightly different in ultraviolet compared to visible light. In UV the flower gets darker towards the centre of the flower, with an area quite a bit darker than the rest of the flower around the centre. The very centre (possibly the tips of petals that have yet to unfurl?) is quite bright.

In visible light the flower gets lighter towards the centre, while the very centre is darker.

In infrared light the flower does not have much tonal variation other than a slight dark ring around the centre of the flower (also present in visible light).
