Scientists at the University of California, Berkeley have developed a technology that can directly stimulate individual photoreceptor cells in the human retina, allowing people to perceive colors that ...

In a study published in Science Advances on Friday, April 18, a group of five researchers stimulated retina cells in participants' eyes, who, afterwards, claimed to have seen a color no human has ...

The rainbow may be due for an update. A new, high-tech method for displaying color has allowed five test subjects to see a shade beyond the standard human range. The research, published April 18 ...

Colour vision is enabled by cone cells in the retina. Most humans have three types of cone cells, known as L, M and S (long, medium and short), which respond to different wavelengths of visible light.

TL;DR: Researchers have discovered a color called "olo," unseen by humans before, by stimulating specific M cones in the retina. This breakthrough bypasses natural RGB limitations, revealing a ...

In a groundbreaking study, scientists have unveiled a new colour named ‘olo’ — a saturated blue-green hue that lies beyond the normal human range of vision. So far, only five people in the ...

These signals are sent to the brain through the optic nerve, allowing humans to perceive images and see the world around them. The retina comprises cone cells - cells that 'perceive' colour. Three ...

And today, I envy five regular human beings who, after having their eye cones temporarily rewired with a laser, were able to perceive a new color outside the typical range of the human eye.

and blue layers — on top of each pixel to create a colour image. But these filters block over 70% of the light that hits them. That means most of the light is wasted, especially in low-light ...
