I have been asked by a member working for their program Jeux Photoniques at the Université Laval in Québec, Canada for a series of images to simulate the vision of different animals. I used images of a Rudbeckia hirta flower Black Eyed Susan - Rudbeckia hirta which I had shot using visible and reflected ultraviolet photography.

1) Humans have trichromatic vision, they see Blue, Green, Red
2) Butterflies see UV, Blue, Green, Red, they are Tetrachromats
3) Bees see UV, Blue, Green, they are Trichomats
4) Dogs are Dichromats, see Blue and Yellow, but also some UV
5) Horses are Dichromats, they see Blue and Yellow, but no UV
6) Bats do not see color, but some are sensitive to UV also
