Address Sign Colors: Which Are Most Visible?

The Science of Sign Visibility

Color contrast is the key factor in sign readability. The greater the contrast between the background color and the reflective numbers, the easier the sign is to read — especially at night.

Color Rankings

1. Blue Background — Best Overall

Blue provides excellent contrast with white reflective numbers in all lighting conditions. It's also the most aesthetically pleasing for most home styles, which is why we named our company Visi Blue.

2. Green Background — Great for Rural

Green stands out well against most surroundings while maintaining a natural look. Popular choice for wooded or rural properties.

3. Red Background — Maximum Urgency

Red grabs attention immediately. Often chosen by properties near fire stations or in areas with frequent emergency access needs.

4. Black Background — Sharp Contrast

Black offers the highest contrast with white reflective numbers. Excellent readability but may blend in with dark surroundings at night.

Our Recommendation

We recommend **blue** for most installations — it offers the best combination of visibility, aesthetics, and contrast. It's why our brand carries the name.

Tips for Maximum Visibility

• Choose a background color that contrasts with your surroundings
• Larger numbers (4") are better for properties far from the road
• Keep signs clean — dirt reduces reflectivity
• Replace signs showing wear or fading
