Geometric fix completes Schrödinger’s color theory after a century
A Los Alamos team mathematically defines the neutral axis and shows hue, saturation and lightness arise from the intrinsic geometry of color, fixing gaps in Schrödinger’s century‑old theory. By using shortest-paths in a non‑Riemannian color space, they correct hue shifts caused by brightness (Bezold–Brücke effect) and strengthen color modeling for visualization and data interpretation.
