OLED and Quantum Dot shows could dominate 2025’s visible tech scene, however essentially the most groundbreaking development isn’t on a display in any respect. Scientists have unveiled ‘olo’—an exceptionally saturated blue-green colour that exists completely exterior the traditional colour spectrum our eyes developed to understand.
Breaking the Visible Barrier
The key lies within the aptly named “OuncesVision System,” drawing inspiration from the Emerald Metropolis in The Wizard of Oz. This system transforms colour notion by selectively stimulating solely the M cone cells within the human retina. Not like Different trendy Best TV shows, which combine completely different wavelengths—the identical fundamental tech powering screens for the reason that rabbit-ear TV period—the Ouncessystem bypasses these limitations completely.
How the Magic Works
The expertise—adaptive optics scanning gentle ophthalmoscopy (AOSLO)—permits for exact focusing on of particular photoreceptors within the eye. By controlling which cone cells obtain stimulation, researchers can create colour perceptions that don’t exist in nature.
“Extra saturated than any color that you may see in the true world,” explains Prof. Ren Ng, co-author of the research and one in every of solely 5 contributors who’ve skilled the colour. In one other interview with the BBC, Ng elaborated with an analogy: “It’s like somebody who has solely seen pale pink being proven purple for the primary time.”
This shift from conventional colour copy strategies represents a transfer from spectral metamerism to spatial metamerism—as an alternative of blending wavelengths to simulate colours, the Ouncessystem controls precisely the place gentle lands on the retina.
Actuality, Expanded
Think about strolling into an artwork gallery the place sure work comprise colours your mind has by no means processed earlier than. Image streaming a film the place the villain wears a shade that doesn’t exist in nature. These purposes stay theoretical for now, however they illustrate the potential of this breakthrough.
The present AOSLO {hardware} is decidedly not consumer-ready—cumbersome, costly, and sophisticated. This laboratory tools bears little resemblance to the smooth, minimalist aesthetic trendy tech customers count on.
As Austin Roorda, a imaginative and prescient scientist on the analysis crew, told NDTV: “There is no such thing as a strategy to convey that color in an article or on a monitor…” The expertise of seeing ‘olo’ stays restricted to laboratory situations and the handful of researchers who’ve instantly skilled it.
Not all specialists agree on the right way to interpret these findings. Some scientists debate whether or not ‘olo’ constitutes a really “new” colour or represents a novel neural response to selective stimulation—a nuance price contemplating amidst the joy.
The Colourful Horizon
For now, ‘olo’ stays confined to specialised labs, however the implications ripple throughout industries. VR builders would possibly sometime create immersive worlds with unimaginable colours. Medical researchers see potential for treating colour imaginative and prescient deficiencies, although these purposes stay theoretical.
Prof. Ng helps contextualize the expertise for individuals who won’t ever see ‘olo’ firsthand: “Think about you undergo life seeing solely pink…then someday…a brand new colour, which we name purple.” This analogy, shared in his BBC interview, provides a glimpse into the profound nature of experiencing a colour exterior our pure visible gamut.
As researchers proceed refining this expertise, one certainty stays: our understanding of visible notion stands on the fringe of transformation. The world would possibly sometime turn out to be extra colourful—in methods we fairly actually can not but think about.
