    en.wikipedia.org/wiki/UV_coloration_in_flowers

    The visible color of the flower impacts the UV color. [9] Yellow flowers having the greatest measure of reflectance. [5] It is more typical to observe UV coloration in purple, red and yellow flowers while white and green ones are less likely. [2] Generally flowers that are white or green tend to be wind pollinated; where being a bright color ...

    en.wikipedia.org/wiki/Evolution_of_color_vision

    Today, most mammals possess dichromatic vision, corresponding to protanopia red–green color blindness. They can thus see violet, blue, green and yellow light, but cannot see ultraviolet or deep red light. [5] [6] This was probably a feature of the first mammalian ancestors, which were likely small, nocturnal, and burrowing.

  4. Trichromacy - Wikipedia

    en.wikipedia.org/wiki/Trichromacy

    Trichromatic color vision is the ability of humans and some other animals to see different colors, mediated by interactions among three types of color-sensing cone cells. The trichromatic color theory began in the 18th century, when Thomas Young proposed that color vision was a result of three different photoreceptor cells .

  5. The term “pollinator syndrome” describes plant characteristics that might appeal to a specific type of pollinator, including color, scent, flower shape, and more. Bees see the world around us ...

  6. Visual perception - Wikipedia

    en.wikipedia.org/wiki/Visual_perception

    The major problem in visual perception is that what people see is not simply a translation of retinal stimuli (i.e., the image on the retina), with the brain altering the basic information taken in. Thus people interested in perception have long struggled to explain what visual processing does to create what is actually seen.

    These animals can see the UV patterns found on flowers and other wildlife that are otherwise invisible to the human eye. Ultraviolet vision is an especially important adaptation in birds. It allows birds to spot small prey from a distance, navigate, avoid predators, and forage while flying at high speeds.

  9. Anthocyanin - Wikipedia

    en.wikipedia.org/wiki/Anthocyanin

    In flowers, the coloration that is provided by anthocyanin accumulation may attract a wide variety of animal pollinators, while in fruits, the same coloration may aid in seed dispersal by attracting herbivorous animals to the potentially-edible fruits bearing these red, blue, or purple colors.
