Human Eyes See New Color “Olo” for the First Time

Scientists have created a technology called Oz that stimulates individual photoreceptor cells in the human eye to create an entirely new, ultra-saturated color never seen in nature—dubbed olo. Using microdoses of laser light, Oz activates specific combinations of cone cells to generate this vivid blue-green hue, which vanishes the moment the precision targeting is disrupted.

How Human Retinas Create a Colorful World

In a groundbreaking study using lab-grown human retinas, researchers unveil the process behind our ability to see millions of colors, a trait unique to humans. The findings challenge previous beliefs and demonstrate how retinoic acid plays a crucial role in determining whether specialized cone cells sense red or green light.

Sea Snakes Regained Color Vision via Rare Genetic Evolution

A new study reveals the annulated sea snake has evolved to perceive a wider range of colors than its ancestors. Early snakes lost their color vision during their adaptation to dim-light burrowing lifestyles, but sea snakes, which inhabit brighter marine environments, regained color vision.

Could We Train Our Brains to See New Colors?

Researchers question if our brains can take in three primary color inputs and turn them into the range of different colors we can see, could a little bit more mental work result in us unlocking different hues?

Our visual world of color is largely incorrect

People are oblivious to change when color is removed from peripheral vision. Research reports the brain likely fills in for much of our perceptual experience when it comes to seeing the entire picture in color.

How do fruit flies see in color?

Researchers have identified a circuit in the brains of fruit flies, which enables them to see in color. The network is similar to that which allows human color vision. The findings could help in the development of AI technologies.
