Quadriptych of human vision, UV, simulated butterfly and bee vision (left to right, top to bottom):

This rose has just a little UV reflection around 380nm, its petals have some UV dark center and the outside part is a bit UV brighter around 380nm and all this gets nicely visible, also in simulated bee and butterfly vision.
Stay tuned, more will follow on that fascinating subject...
