Knowledge boundary
- Source: content/projects/itten-color-contrasts/experiment-report/EX-ITTEN-007-peripheral-chromatic-cues.md
- Status: model-simulation-complete-gaze-study-pending
- Discipline: Measurement
- Confidence: not explicitly stated
- Primary objective: What cue size and contrast are needed for alerts under divided attention and realistic motion? The hue-fragility prediction fails if hue-only detection remains invariant with eccentricity after retinal size and luminance are controlled.
- Primary claims/evidence: At the lowest modeled chroma, the minimum was .25° foveally, .5° at 5°, 2° at 10°, and no tested size passed at 20° or 30°. At 20°, only the two highest chroma levels passed, both at 1° ; no condition passed at 30°. These are model predictions, not thresholds.
- Methodology: At the lowest modeled chroma, the minimum was .25° foveally, .5° at 5°, 2° at 10°, and no tested size passed at 20° or 30°. At 20°, only the two highest chroma levels passed, both at 1° ; no condition passed at 30°. These are model predictions, not thresholds.
- Limitations/known uncertainties: Question and falsifier: What cue size and contrast are needed for alerts under divided attention and realistic motion? The hue-fragility prediction fails if hue-only detection remains invariant with eccentricity after retinal size and luminance are controlled.

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.
