RFR-39B8813B — Calibrate construct and measurement validity: Itten Color Contrasts — Research Cycle 1

Research opportunity

Calibrate construct and measurement validity for the claims or recommendations in “Itten Color Contrasts — Research Cycle 1.”

Background

The originating artifact is accepted by the repository publishing inventory with status “complete.” Its Question section provides the immediate evidence boundary.

Evidence trace

• Origin document: content/projects/itten-color-contrasts/research-journal/2026-07-28-cycle-1.md
• Section: Question
• Specific assumption challenged: The source's treatment in “Question” is sufficiently supported for its intended scope.
• Supporting evidence excerpt: “Which of Itten's seven contrasts remain scientifically defensible, what mechanisms and boundaries replace his explanations, and which claims should become engineering rules?”
• 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-RJ-VE-ITTEN-001-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.

Evaluation

Confidence in this opportunity: moderate. Status: Open.
