Is this a safety guarantee?

This guidance is based on local street-scene analysis and general visibility principles. It is not a prediction of crash risk or a guarantee of safety.

Why local results differ

  • Brick, vegetation, glass, painted surfaces, asphalt, sky, and shade can change which clothing colors separate from the background.
  • Daytime pages weigh color contrast against the local backdrop; low-light pages are more conservative and emphasize brightness, reflectivity, and lights.
  • Routes with tunnels, tree cover, rain, dusk, or heavy traffic can differ from the average local image sample.

What to do

  • Start with one high-contrast top layer that reads clearly against the local street palette.
  • Keep reflective details on motion points if your route continues into shade, dusk, or traffic-heavy areas.
  • If you are biking, avoid relying on clothing color alone when the route includes tunnels, tree cover, or sunset transitions.

If you are choosing from regular clothing, start with white and add reflective details at moving points. It lands at about 85% of the average high-vis score here.

If you are packing one option for Seaport / South Boston daytime conditions, make it white if that is what you already own. If you have high-vis gear, fluorescent yellow still performs best overall.
