Jaw Dropping Moment! Scientists Discover New Color Olo That No Human Has Seen Before; Know Everything About It

The scientists of University of California has made an astounding discovery, something that no human has ever seen before. For the first time ever, these scientists have claimed to find a new color, an impossibly saturated bluish-green shade. The new jaw-dropping color was found after creating an extensive test with five humans as subjects, making them the first ones to witness this new color.

The details of the new color was published in a paper in Science Advances on Friday.

In the paper, it said, "We introduce a principle, Oz, for displaying color imagery: directly controlling the human eye's photoreceptor activity via cell-by-cell light delivery. Theoretically, novel colors are possible through bypassing the constraints set by the cone spectral sensitivities and activating M cone cells exclusively."

In practice, the scientists confirmed a partial expansion of colorspace toward that theoretical ideal. Attempting to activate M cones exclusively elicits a color beyond the natural human gamut, formally measured with color matching by human subjects. They describe the color as blue-green of unprecedented saturation. Further experiments show that subjects perceive Oz colors in image and video form. The prototype targets laser micro doses to thousands of spectrally classified cones under fixational eye motion. These results are proof-of-principle for programmable control over individual photoreceptors at the population scale.

According to the paper, in principle, arbitrary colored visual imagery can be displayed by this cell-by-cell approach, but doing so requires exquisite precision in reproducing the dynamic stimulation levels at each photoreceptor as imagery traverses the retina under eye movements. As proof of principle, we perform human subject experiments on a prototype Oz system that stimulates thousands of retinal cone cells.

Theoretically, Oz enables the display of colors that lie beyond the well-known, bounded color gamut of natural human vision (1). In the normal color vision, any light that stimulates an M cone cell must also stimulate its neighbouring L and/or S cones, because the M cone spectral response function lies between that of the L and S cones and overlaps completely with them. However, Oz stimulation can target light to only M cones and not L or S, which in principle would send a color signal to the brain that never occurs in natural vision. Theoretically, Oz expands the natural human color gamut to any (L, M, and S) color coordinate, it said.

In practice, the scientists achieved a partial expansion of color space toward this theoretical maximum.

Lastly, the paper said, "Oz represents a new class of experimental platform for vision science and neuroscience, which strives for complete control of the first neural layer to the brain, programmability of every photoreceptor's activation at every point in time. Our prototype is an advance toward this class of neural control, and we demonstrate its ability to accurately deliver microdoses to target cones despite the challenges presented by constant fixational eye motion and the optical aberrations of the eye. When Oz microdoses are intentionally "jittered" by just a few microns, subjects perceive the stimulating laser's natural color. When these same Oz microdoses are delivered accurately, subjects can be made to perceive different colors of the rainbow, unprecedented colors beyond the natural human gamut, and imagery like brilliant red lines or rotating dots on an olo background."

Thereby, this new class of programmable platform will enable diverse new experiments.
