Achromatic Cues Are Important for Flower Visibility to Hawkmoths and Other Insects

Frontiers in Ecology and Evolution, 2022
Studies on animal colour vision typically focus on the chromatic aspect of colour, which is related to the spectral distribution, and disregard the achromatic aspect, which is related to the intensity (“brightness”) of a stimulus.
