I was shooting Zinnias today, when I saw one which sported that greenish short wave UV-A sub band reflection as mentioned here before..

Standardized reflected false UV "colors" according to the previously described "UV color palette" related to wavelength.
The normal and high intensity palette:
The reflected UV image shows that this Zinnia flower variant has a greenish / yellowish short wave UV-A reflection in the 340-360nm range:
VIS shot for comparison:
Stay tuned, more will follow on that fascinating subject...

[UV, VIS] Zinnia flower competing
I was shooting Zinnias today, when I saw one flowering aside another bright yellow flower. I noticed the Zinnias being frequently visited by bees and bumblebees, whereas the similar looking yellow one had only few guests.

Standardized reflected false UV "colors" according to the previously described "UV color palette" related to wavelength.
The normal and high intensity palette:
Well, the reflected UV image shows clearly how that Zinnia flowers wins the "competition":
Even covered by other plants it makes itself clearly seen (see blurry BG Zinnia). So not really "competition" for that UV-bright Zinnia (340-360nm).
Stay tuned, more will follow on that fascinating subject...
