Calibrate construct and measurement validity: Color-Difference Metric Validation
RFR-D474F814 — Calibrate construct and measurement validity: Color-Difference Metric Validation
Research opportunity
Calibrate construct and measurement validity 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 Work completed 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:
Work completed - Specific assumption challenged: The source's treatment in “Work completed” is sufficiently supported for its intended scope.
- Supporting evidence excerpt: “Three thousand fixed-seed random sRGB pairs were compared with Euclidean Lab and Oklab before and after a simple gamut-compression transform. Rank stability and relation to luminance difference were recorded.”
- Reason this opportunity exists: Whether the document's operational measures isolate the intended construct rather than a correlated proxy or decision strategy.
Unknowns
- Whether the document's operational measures isolate the intended construct rather than a correlated proxy or decision strategy.
Dependencies
- None; this is foundational work.
Suggested REP and methodology
- Suggested REP:
REP-EX-ITTEN-008-MEASUREMENT - Methodology: Define the construct, compare convergent and discriminant measures, estimate reliability, test measurement invariance, and publish calibration data.
- Expected outputs: Construct definition, measurement protocol, reliability study, calibration dataset, and validity report.
- Success criteria: Measures meet declared reliability and validity thresholds across the principal populations and contexts.
- Recommended agent:
measurement-research-agent - Estimated effort: Medium
- Expected knowledge gained: Whether the document's operational measures isolate the intended construct rather than a correlated proxy or decision strategy.
