Independent validation of the central claim: Color-Difference Metric Validation
RFR-C872668D — Independent validation of the central claim: Color-Difference Metric Validation
Research opportunity
Independent validation of the central claim for the claims or recommendations in “Color-Difference Metric Validation.”
Background
The originating artifact is accepted by the repository publishing inventory with status “computational-stress-test-complete-ground-truth-study-pending.” Its Pilot results section provides the immediate evidence boundary.
Evidence trace
- Origin document: content/projects/itten-color-contrasts/experiment-report/EX-ITTEN-008-color-metric-validation.md
- Section:
Pilot results - Specific assumption challenged: The source's treatment in “Pilot results” is sufficiently supported for its intended scope.
- Supporting evidence excerpt: “Rank stability after the mild compression was .9990 for Lab and .9987 for Oklab. Cross-metric rank correlation was only .7824 . Correlation with luminance difference was .3675 for Lab and .7417 for Oklab in this generated corpus. The stress transform was too mild to separate within-metric robustness, but the cross-met…”
- Reason this opportunity exists: Whether the central claim survives preregistered, independent testing under explicitly bounded conditions.
Unknowns
- Whether the central claim survives preregistered, independent testing under explicitly bounded conditions.
Dependencies
- None; this is foundational work.
Suggested REP and methodology
- Suggested REP:
REP-EX-ITTEN-008-VALIDATION - Methodology: Preregister hypotheses, sampling, exclusion rules, measures, and analysis; reproduce the claimed effect with an independent implementation and report effect sizes and uncertainty.
- Expected outputs: Preregistration, replication dataset, analysis code, effect-size report, and claim-status decision.
- Success criteria: The study has adequate power, reproducible materials, explicit failure criteria, and updates the originating claim regardless of outcome.
- Recommended agent:
validation-research-agent - Estimated effort: Large
- Expected knowledge gained: Whether the central claim survives preregistered, independent testing under explicitly bounded conditions.
