"textContent": "\n\n\nScientists have cracked a mathematical puzzle, completing a theoretical framework for understanding how humans perceive colour.\n\nThe Los Alamos National Laboratory, headed by Roxana Bujack, employed geometric principles to construct a rigorous mathematical definition of colour perception.\n\n###\n\n\n\n\nThe research was built around the three fundamental qualities of hue, saturation and lightness.\n\nTheir findings, unveiled at a visualisation science conference, demonstrate Erwin Schrödinger's pioneering work from the 1920s can now be considered formally complete.\n\n###\n\n\n\n\nTRENDING\n\nStories\n\nVideos\n\nYour Say\n\n###\n\n\n\n\nThe breakthrough reveals the hidden geometric structure underlying human colour vision.\n\nPerhaps most significantly, the research establishes these familiar colour qualities are not shaped by cultural background or learned behaviour but are instead fundamental properties woven into the very fabric of colour perception.\n\nDr Bujack said: \"What we conclude is that these colour qualities don't emerge from additional external constructs such as cultural or learned experiences but reflect the intrinsic properties of the colour metric itself.\"\n\nShe explained this metric encodes perceived colour distance geometrically, essentially measuring how different two colours appear to someone observing them.\n\n###\n\n\n\n\n###\n\n\n\n\n###\n\n\n\n\nThe team's objective was to define hue, saturation and lightness purely through the geometric principle of maximum colour similarity.\n\nHuman colour vision relies on three types of cone cells sensitive to red, blue and green, creating a three-dimensional colour space scientists can analyse mathematically.\n\nIn the nineteenth century, Bernhard Riemann proposed these perceptual colour spaces possess curved rather than flat geometry.\n\nThis concept later developed into Schrödinger's model.\n\n### LATEST DEVELOPMENTS\n\n\n\n\n * Astronauts told to prepare for urgent ISS evacuation after air leak\n * Army veteran pays off mortgage after using metal detector to find rare gold Roman ring\n * Stonehenge altar may have travelled hundreds of miles away, scientists believe\n\n\n\n###\n\n\n\n\n###\n\n\n\n\nHowever, the Los Alamos researchers discovered a critical flaw whilst developing visualisation algorithms.\n\nSchrödinger had never formally defined the neutral axis, the grey line stretching from black to white.\n\nSince his definitions of hue, saturation, and lightness all depend on a colour's position along this axis, the omission left the entire framework mathematically incomplete.\n\nThe team's central achievement was establishing a precise definition of this neutral axis using only the geometry of the colour metric.\n\n###\n\n\n\n\n###\n\n\n\n\n###\n\n\n\n\n###\n\n\n\n\nThis required them to venture beyond traditional Riemannian mathematics.\n\nThe researchers also addressed two additional shortcomings in the original framework, including the Bezold-Brücke effect, where shifting light intensity causes colours to appear to change hue.\n\nA more accurate model of colour perception holds considerable promise for industries dependent on precise colour reproduction, from photography and video production to data visualisation technologies.\n\nThe work was presented at the Eurographics Conference on Visualization and extends earlier Los Alamos research that produced a significant paper in the Proceedings of the National Academy of Sciences in 2022.\n\nFunding came from the Laboratory Directed Research and Development programme at Los Alamos and the National Nuclear Security Administration's Advanced Simulation and Computing programme.\n\n###\n\n\n\n\n**Our Standards: The GB News Editorial Charter**",
