Described as a kind of blue-green, the new color—named “olo”—can only be seen using lasers to manipulate certain photoreceptors.

A team of scientists in California say they have discovered a new color they named Olo, but you can't see the "most intense teal" with the naked eye.

Researchers behind a recent study claim to have discovered a new color that the natural, naked eye cannot perceive — 'olo,' a hyper-saturated blue-green that occurs when a single kind of cone cell is stimulated in the retina.
