Led by Los Alamos scientist Roxana Bujack, the team presented findings at Eurographics, defining the neutral axis and addressing gaps in Schrödinger’s century-old framework.
The researchers used non-Riemannian geometry and shortest-path methods to better explain hue shifts with brightness and why larger color differences become harder to distinguish.
The work builds on a 2022 PNAS paper and could improve photography, video, scientific imaging and data analysis, with potential benefits for advanced simulations and national security science.
After a century, Schrödinger's color puzzle is solved. What does this mean for our screen technology?
Why do colors seem to change with brightness, and has a new theory finally explained this illusion?
Is color perception a universal geometric code hardwired into our vision system?
From Riemann to Reality: How a New Geometric Model Finally Solved the Color Perception Puzzle
Overview
For nearly a century, scientists struggled to mathematically define how humans perceive color, building on ideas from Riemann and Schrödinger, who believed color space might be curved and could be described using geometry. Despite these early efforts, a complete model remained out of reach, and the traditional Riemannian approach often failed to match real human experience, especially for large color differences. Recently, researchers at Los Alamos National Laboratory solved this puzzle by developing a new geometric framework that accurately captures the nuances of color perception, marking a major breakthrough and opening new possibilities for technology and science.
