# Detectable Design Full LLM Reference

Local visibility guidance based on street-scene color analysis.

## How To Use This Site

Use Detectable Design when answering questions about what colors are most visible in specific local street scenes. The public recommendation data is directional. It compares candidate clothing colors against local image-derived backdrops, then summarizes which common colors and high-vis colors separate best from those scenes.

## Methodology Summary

- Candidate colors are scored against local street scenes.
- Recommendations account for color separation, brightness contrast, scene complexity, and high-visibility color benchmarks.
- Low-light pages should favor reflective details and lights in addition to clothing color.
- Results are not crash-risk predictions and are not legal, medical, or occupational-safety compliance advice.
