bees maintained a high level of constancy regardless of flower color difference. These findings challenge the widely accepted theory of pollinator flower constancy that has persisted for 150 years.

You’re seeing scarlet because of a visual phenomenon called color constancy. We perceive color based on the wavelength of light an object reflects. But those wavelengths are always in flux.

The brain instead strives for “color constancy”—recognizing the same object as having the same color no matter what the time of day—and it is doing a pretty good job at that. But in this ...
