If you've ever looked at a rack of hi-vis vests and wondered, "Is blue actually allowed?"—you're not the only one. Hi-vis safety gear is usually bright yellow or orange, but blue has become more popular for teams that want to stand out (or match their brand colours). The big question: Is a blue high-vis vest safe to wear? Let's break it down – no jargon, just straight answers for workers, employers and safety managers.
First Things First: Legal Compliance Isn’t About Color (Mostly)
The important thing to know is that OSHA (US), EN ISO (EU) and other global safety bodies do not ban blue hi-vis vests. Instead, they focus on two things that matter much more than colour:
1.Retroreflectivity: The vest must have reflective tape that bounces light back to the source (e.g., car headlights) in low-light conditions.
2.Luminance (brightness): The fabric must be bright enough to be seen in daylight, even from far away.
To put it simply, you can wear a blue high-vis vest as long as it meets these performance standards. Orange and yellow are popular because they're easy to see, but blue can work too – especially if it's a bright, strong shade of blue (like "safety blue" rather than a dark navy).
Regional Rules to Know
Let’s dive into the specifics for major markets:
US (OSHA)
OSHA’s Standard 1926.407 (construction) and 1910.132 (general industry) require “high-visibility apparel” for workers in high-risk areas (e.g., near traffic, heavy machinery). There’s no color restriction—only that the vest meets ANSI/ISEA 107 (the gold standard for hi-vis gear). Blue vests certified to ANSI/ISEA 107 are 100% legal.
EU (EN ISO 20471)
EN ISO 20471 classifies hi-vis vests into Classes 1-3 (based on coverage and reflectivity). Blue is allowed, but the fabric must meet minimum luminance values (measured in cd/m²). Pro tip: Look for the EN ISO 20471 certification label—this is your proof of legality.
Australia (AS/NZS 4602.1)
Similar to the EU and US: Color isn’t restricted, but the vest must be AS/NZS 4602.1 certified. Blue is commonly used in mining, logistics, and utility sectors.
When Blue Hi-Vis Vests Shine (Literally)
Blue isn't just legal—it's a smart choice for certain teams.
•Brand Alignment: Companies with blue logos (e.g. logistics firms, tech teams) can keep safety gear on-brand without breaking the rules.
•Clear roles: At big work sites (like airports and warehouses), blue can show the different teams (like maintenance and security) while keeping everyone easy to see.
•Low-Light Environments: Bright blue is just as effective as orange at standing out against dark backgrounds, such as those found in night shifts or indoor warehouses, when used with quality reflective tape.
The Catch: Avoid These Blue Hi-Vis Mistakes
Blue vests come in different sizes. To stay within the law, avoid doing the following:
•Muted Shades: Navy, dark blue, or "pastel blue" are not suitable because they do not meet the required brightness levels. Instead, you should choose a bright, vivid blue (often labelled "safety blue" by the people who make the products).
•No Reflective Tape: A plain blue shirt isn't brightly coloured! Legal vests need retroreflective tape (usually silver or yellow) on the chest, back and shoulders.
•Uncertified Gear: If the vest doesn't have ANSI/ISEA, EN ISO, or regional certification, it doesn't meet legal standards — even if it's bright blue.

FAQs: Your Blue Hi-Vis Questions Answered
Question: Is it allowed to wear a blue high-vis vest on a construction site?
A: Yes, if it's ANSI/ISEA 107 certified (US) or EN ISO 20471 (EU). Check with your employer for rules that apply to your site (some prefer orange/yellow for uniformity).
Q: Is blue hi-vis less visible than orange?
A: No, it's not. Orange/yellow are more visible in daylight, but blue performs well in low light (with reflective tape).
Q: What shade of blue do I need?
A: Yes—look for "safety blue" or "high-visibility blue" (avoid dark or dull blues). Our team at safetycustom.com can help you choose the right shade for compliance.
