Fruit flies are a powerful model for studying the color vision process as they are amenable to very specific genetic manipulations, allowing researchers to analyze how the visual system functions when different elements of the retina are affected. “This simple insect can achieve sophisticated color discrimination and detect a broader spectrum of colors than we can, especially in the UV,” says NYU biologist Claude Desplan.

NYU (US)—Biologists have identified, in greater detail, how the retina’s cellular hardware is used in color preference. The work enhances our understanding of how eyes and the brain process color. Continue…

Applying math to color our world
A. Kimball Romney’s recent research led to a mathematical visualization of cone photo receptor sensitivities. His work could advance efforts to display uniform, high-quality color in a variety of fields. (Credit: Daniel A. Anderson)
