Frontier analysis — Color-Vision Deficiency, Aging, and Redundant Encoding — Itten Color Contrasts / Experiment Report / EX ITTEN 004 Cvd Aging Redundancy
Knowledge boundary
- Source: content/projects/itten-color-contrasts/experiment-report/EX-ITTEN-004-cvd-aging-redundancy.md
- Status: simulation-audit-complete-human-study-pending
- Discipline: Measurement
- Confidence: stated in source; mixed
- Primary objective: Do redundant encodings preserve consequential task performance across aging and congenital CVD better than color-only encodings? The redundancy principle fails if a well-powered representative study finds no performance or error-resilience advantage.
- Primary claims/evidence: Modeled detectable-pair proportions declined from 1.000 to .9848 for typical vision, .9697 to .9394 for protan simulation, .9242 to .8788 for deutan simulation, and remained .9394 in the simplified tritan transform. The coded shape-redundancy channel remained 1.0 by construction. These are audit flags only. The cutoff, matrices, yellowing transform, and perfect shape detection are assumptions. The result supports selecting difficult pairs for a study; it does not estimate clinical detection rat…

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.
