Humans rely on sight, which is primarily mediated by three color-sensing cone types, to perceive the world in a kaleidoscope of hues. Blue cones develop earliest, followed by the morphologically ...

Scientists have created a color that lies outside the range of normal human vision. Using laser pulses to stimulate specific cells in the retina, a team from UC Berkeley and the University of ...

Technology used by UC Berkeley researchers to see a new color may allow for development of new ways to see and research eye diseases. The machine, dubbed Oz, was previously used to shoot lasers into ...

A team of scientists has found a way to unlock a color that doesn't exist in the natural world. Named "olo," this new shade has only been seen by five people so far. It's described as a vivid ...

In the retinas of human eyes, the cones are photoreceptor cells responsible for color vision, daylight vision, and the perception of small details. As vision scientists from the Division of ...

UC Berkeley computer scientists and vision scientists have developed a technology that enables the human eye to see a new color. The color is an extremely bright green-blue hue called “olo” that is ...

A new experiment into color vision has allowed a select group of human subjects to see a new color. Subjects describe the “unprecedented” color as a very saturated teal. Researchers are looking into ...

Daltonism is a specific type of red-green color vision deficiency, also known as color blindness. People with red-green color vision deficiency may confuse colors that contain red or green elements.

The most common types of color blindness, or color vision deficiency, are genetic. However, other types may develop due to injuries, eye diseases, health problems, and side effects of treatment.
