Knowledge boundary

• Source: content/projects/project-atlas/research-note/rp-atlas-color-004-munsell-vs-modern-perceptual-color-spaces.md
• Status: Research Execution Package
• Discipline: Measurement
• Confidence: High on architectural conclusions; moderate on comparative performance outside tested datasets
• Primary objective: Albert H. Munsell's enduring contribution was not a perfect color solid. It was the decision to separate color description into three ordered attributes: - hue - value - chroma and to space physical samples by visual judgment rather than by geometric or pigment theory alone. That move survives in nearly every later perceptual color system. The investigation produced five major conclusions. 1. Munsell's conceptual decomposition survives. Modern spaces still separate a lightness-like coordinate f…
• Primary claims/evidence: Albert H. Munsell's enduring contribution was not a perfect color solid.

• Methodology: Determine which parts of Munsell survived modern color science and build the first Atlas Perceptual Measurement Layer.
• Limitations/known uncertainties: Largest Remaining Unknown: Which measurement stack best predicts functional UI outcomes rather than laboratory color-pair judgments?

Five highest-value opportunities

Challenge and confidence decay

The source was challenged for construct validity, independent replication, boundary conditions, transfer, and comparative baselines. Confidence should decay when the source lacks a dated replication, when its technology or target population changes, or when later artifacts report contradictory findings. Revalidation is recommended before treating context-bound recommendations as universal.
