Here shots of a Clivia miniata flower. This flower exhibits some different longer wave UV reflection, in blue/violet color corresponding to a about 385-395nm UV reflection in the deep center and whitish color i.e. UV reflection around 370-375nm from the middle to the petal tip (cf my false color UV palette).

This UV image here also uses my Standardized false UV color normal + high intensity palette:
A spectrometric confirmation of these above mentioned assumptions concerning the reflectivity of this flower petal is here:
The max. reflection of the whitish tip in UV using my standardized false UV color palette is around 373nm and the deeper parts of the petal which looks violet has its maximum at 389nm which both confirms the expectations mentioned above.
Stay tuned, more will follow on that fascinating subject...
