Schrödinger’s color theory finally completed after 100 years
General • February 23, 2026
A
century after Erwin Schrödinger sketched out a bold
vision for how we
perceive color,
scientists have finally filled in the missing pieces. A Los Alamos team used advanced geometry to show that hue, saturation, and lightness aren’t shaped by culture or experience — they’re built directly into the mathematical structure of how we see color. By defining a crucial missing element known as the “neutral axis,” the researchers repaired a long-standing flaw in Schrödinger’s model and even corrected tricky visual quirks like the way brightness can subtly shift perceived hue.
