Prior investigations have failed to clarify whether color constancy is an innate capability of the retina's cone cells or it's acquired only with help from the brain's visual system.
Yoichi Sugita of the Neuroscience Research Institute in Tsukuba, Japan, explored color constancy in four macaque monkeys that had been raised from age 1 month to 1 year in a room illuminated by light with a highly restricted range of wavelengths, which ensured that the animals couldn't discern a normal array of colors.
His report is the first clear demonstration that animals can perceive colors, which indicates working cone cells in the retina, but that they lack the capacity for color constancy, comments Stanford University vision researcher Brian A.

With optimized color constancy, the swatches are individually packaged and are free of any backing paper or adhesives that affect the color appearance and spectral readings.
Outperforming the color constancy and brightness of previous LED designs, 6-lead MultiLEDs can be arranged closely together and flat on the board, resulting in light that is distributed more evenly.
