• Status: active-research-package
• Discipline: Measurement
• Confidence: medium-high
• Primary objective: Itten’s seven contrasts survive best as phenomenological prompts , not as seven scientifically distinct laws. Modern evidence supports the existence of the perceptual effects behind hue separation, light–dark organization, complementary adaptation, simultaneous induction, and chroma differences. It does not support Itten’s implied mechanistic independence, universal prescriptions, or fixed proportional harmonies. The decisive revisions are: 1. Light–dark is primary for legibility and structure.…

• Methodology: This review treats an “objective” principle as one that yields operationalized, repeatable predictions under specified stimulus, observer, task, and viewing conditions. It does not require culture-free conscious descriptions; it does require more than historical authority or preference. Cycle 1 searched primary psychophysics, vision-science, color-appearance, accessibility, and display standards sources, with priority given to reviews, cross-cultural tests, and sources exposing boundary conditi…
• Limitations/known uncertainties: Research gaps and experiment program: All eight experiments below now have reproducible computational/planning pilots, individual result reports, continuation state, and executable protocols. This does not mean the empirical experiments are complete: no human participants or p… Confidence, falsification, and saturation: High-confidence conclusions are the relational nature of appearance, the importance of luminance/spatial structure, sensory opponency, adaptation, contextual induction, and the need for non-color redundancy. Medium-confidence conclusions c… Limitations: This package does not reproduce Itten’s original plates or quantify his exact historical area ratios. It does not claim that one color space is uniformly best. It does not equate standards conformance with usability. Several mechanism lite…

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.
