Scientists in California claim to have discovered a new jaw-dropping color no human has ever seen before.

In a groundbreaking study published in *Science Advances*, researchers from the University of California, Berkeley, have unveiled a color dubbed 'olo,' which has never been experienced by human eyes. This astonishing revelation was made possible through advanced laser technology that selectively stimulates the retina's cone cells, allowing individuals to perceive a blue-greenish hue with saturation beyond the capabilities of natural human sight. According to Ren Ng, a computer scientist and co-authored scientist involved in the study, the experience of 'olo' is entirely unique, describing it as vastly more vibrant than any colors currently visible to humans. The methodological innovation involved the application of microdoses of laser light that targeted the M cone cells responsible for greenish-light perception. By isolating this stimulation, the scientists aimed to question the conventional understanding of color by facilitating the perception of an entirely new hue. The results confirmed that the perception of a new color is not only conceivable but also achievable, illustrating the extraordinary potential of this scientific breakthrough. Austin Roorda, a vision scientist on the team, emphasizes that this color cannot be adequately expressed through text or screens, illustrating the limitations of current technology in conveying human experiences of color. It’s a reminder of the vast complexity and the potential of human perception. Moreover, the researchers foresee possible applications of this technology extending beyond mere color perception. Ren Ng also notes that the method could lead to advancements in treating color blindness, a condition that affects millions worldwide without effective remedial options. However, the researchers acknowledge the current limitations of the method, noting that it can only be applied effectively to a small area of the visual field, and the technology is not yet widely accessible. This revelation underscores not only the achievements of the research team but also opens avenues for further exploration in neuroscience and visual technology. Although there are challenges ahead in terms of practical application and availability, the work is being hailed as a remarkable technical feat, with the potential to reshape our understanding of color perception in both scientific and medical fields. As the team prepares for the complexities of scaling up their discoveries, this achievement heralds a new chapter in our exploration of vision and the incredible capabilities of the human sensory experience.
