Color Quality Monitoring
3 min read
Color quality is monitored at three levels: individual asset compliance, batch consistency, and long-term palette health.
Individual compliance: every asset passes the brand critic's color evaluation — palette membership, proportion ratios, contrast ratios, darkness level adherence. This is the baseline.
Batch consistency: within a batch of 20 assets, the average color deviation from the palette specification should be less than 2 delta-E (the perceptual color difference unit in OKLCH). If the batch average exceeds 2 delta-E, the generation model is drifting — reanchor to reference images.
Long-term palette health: monthly, sample 50 assets from across the library and measure the aggregate palette distribution. Is the proportion of cyan accent trending up (over-saturation) or down (under-use)? Is the amber secondary appearing more frequently than the 3-5% target? Is the darkness level distribution shifting toward Level 2-3 when it should be predominantly Level 0?
The monitoring dashoard plots these three levels on a single view: a green/yellow/red status for individual compliance, a batch consistency trend line, and a monthly palette distribution heat map. Color quality health at a glance.
