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":

Stay tuned, more will follow on that fascinating subject...
