Hi-Vis Vest Colours Explained: A Guide to Colour-Coding Roles in a Large Factory

On a busy factory floor, you often need to know who someone is before you’re close enough to read their name badge. Is that person a visitor who shouldn’t be near the machinery, a trained first aider, or the shift supervisor? A colour-coded hi-vis system answers all of those questions from thirty metres away, and it’s one of the simplest, cheapest safety improvements a large site can make.

This guide walks through how factories use hi-vis vest colours to identify roles. It starts with single-colour vests for general staff and specific duties, then moves up to the dual-colour executive vests that mark out supervisors and management. It also covers the one thing people most often get wrong: the difference between a vest that looks distinctive and a vest that’s actually certified to keep someone visible around moving vehicles.

Why colour-code hi-vis vests at all?

In a small workshop, everyone knows everyone. In a large factory, distribution centre or manufacturing plant with hundreds of people across multiple shifts, plus contractors and visitors coming and going, that breaks down fast. A colour-coded vest scheme solves several problems at once:

• Instant role recognition. Supervisors, first aiders, fire wardens and forklift operators can be spotted immediately in an emergency or when a decision is needed.
• Controlling access. A different colour for visitors and contractors makes it obvious when someone is somewhere they shouldn’t be.
• Managing new starters. A dedicated “new starter” or “trainee” colour tells everyone nearby to keep an extra eye out and not assume the wearer knows the site’s hazards yet.
• Traffic and pedestrian separation. On sites with forklifts and MHE, being able to distinguish pedestrians, banksmen and drivers reduces the risk of collisions.

The key point is that colour becomes a language. Once staff are trained on what each colour means, the whole workforce can read the floor at a glance.

First, the safety standard: EN ISO 20471

Before assigning colours to roles, it’s worth understanding what “hi-vis” legally means. In Ireland and across the EU, high-visibility clothing is governed by EN ISO 20471, which rates garments by class based on how much fluorescent background fabric and reflective tape they carry:

• Class 3 is the highest level of conspicuity, typically jackets or coveralls with sleeves.
• Class 2 is the standard for most hi-vis vests, suitable where there is vehicle or traffic risk.
• Class 1 is the lowest level, for lower-risk environments.

With that in mind, here’s how the colours are typically put to work.

Single-colour vests and the roles they signal

Single-colour vests are the backbone of any colour-coding scheme. They’re inexpensive, easy to stock in volume, and each colour can carry a clear meaning. There’s no single legal standard that dictates “blue means X”, as each site sets its own scheme. But years of common practice across manufacturing and logistics have produced a widely recognised set of conventions:

This is exactly why a broad colour range is so useful. Our Yoko hi-vis vest in 12+ colours was made for this kind of scheme. It’s the same trusted HVW100 vest in lime, red, royal blue, sky blue, paramedic green, pink, purple, maroon, white and more, so you can map a colour to every role on your site while keeping one consistent, reliable garment across the workforce. It carries two 5cm reflective tapes and hook-and-loop front fastening, and depending on the colour it meets Class 2 (solid hi-vis shades) or Class 1 (split and non-hi-vis colours).

You’ll find the full range of plain and coloured options in our Hi Vis Vests category.

Building your own colour code

A colour scheme only works if it’s documented and consistent. A few practical rules:

• Keep it simple. Five or six colours that everyone remembers beats a dozen that no one does.
• Put it on the wall. A printed key at every entrance, in the canteen and in the induction pack means visitors and contractors learn it immediately.
• Reserve a colour for the untrained. A “new starter” colour for the first few weeks is one of the highest-value choices you can make.
• Don’t sacrifice visibility for identity. Where vehicles operate, keep people in certified yellow or orange and add identity another way, such as printed job titles, coloured armbands or the two-tone executive vests below.

Dual-colour executive vests: marking out supervisors and management

Once you move up from the shop floor to team leaders, supervisors, site managers and health & safety officers, a plain single-colour vest often isn’t enough. This is where executive vests come in, and they solve two problems at once.

First, they’re built as proper workwear rather than a throwaway tabard, with a full-length zip, multiple pockets, a pen pocket, a phone pocket and, crucially for anyone moving between the floor and the site office, a sideloading ID card holder. Deep armholes and a generous cut mean they can be worn over a jacket or blazer, which suits managers who are in and out of meetings.

Second, the two-tone colour design does the identification job automatically. A hi-vis yellow or orange top half keeps the wearer certified and visible, while the contrasting lower panel (navy, black, grey or royal blue) instantly marks them out as someone in charge. You get conspicuity and role recognition in a single garment, without compromising on the safety standard.

Our Yoko executive hi-vis vest is the most flexible option here, with 20+ colour choices including professional two-tone combinations like yellow/navy, orange/black and yellow/grey, plus an ID card holder and full-length zip. Hi-vis yellow, orange and yellow/orange combinations meet Class 2, while two-tone and non-standard colours meet Class 1.

Yellow vs orange two-tone: which for which team?

When you want a dedicated, purpose-built two-tone garment for your management tier, we stock two focused options built on the Supertouch H-series. Both feature band-and-brace reflective, a sideloading ID pocket, front zip, pen pocket, key hook, a phone pocket and multiple flap-and-Velcro pockets, and both are rated Class 2:

• Hi Vis Yellow 2 Tone Executive Vest, yellow paired with royal blue, grey, black or navy. Yellow reads as the standard site colour, so this suits production supervisors, line leaders and shift managers working inside the plant. Sizes S to 4XL.
• Hi Vis Orange 2 Tone Executive Vest, orange with navy, royal blue, black, lime or grey (plus a red/grey option). Orange is the natural fit for yard, logistics, goods-in and traffic-facing supervisors, keeping your management colour scheme aligned with the base vests their teams already wear. Sizes S to 4XL.

A common approach is to mirror the base-vest colour. If your warehouse operatives wear orange, put the warehouse supervisor in an orange two-tone; if your production floor runs on yellow, the production supervisor wears a yellow two-tone. The team’s colour and the manager’s colour stay in the same family, so the hierarchy reads cleanly.

Make the colour code do double duty: add printing

Colour tells people a role from a distance, and printed or embroidered text confirms it up close. Adding “FIRST AID”, “FIRE WARDEN”, “SUPERVISOR”, “VISITOR” or your company logo to the back and chest turns a colour-coded vest into a complete identification system, and reinforces the scheme for anyone still learning it.

Every vest above can be customised in-house with text or your logo, whether that’s a single supervisor’s vest or a bulk order for the whole plant. Because everything is decorated on-site, you can keep the whole workforce consistent and re-order the same spec whenever you take on new staff.

The takeaway

A hi-vis colour code is one of the easiest wins in factory safety, turning a wall of identical vests into a readable map of who does what. Start with certified yellow or orange as your visibility base, assign single colours to clear roles like first aid, fire response and visitors, and use dual-colour executive vests to mark out supervisors and management without giving up on the safety standard. Document it, put a key on the wall, and add printing to lock it in. Your whole team will then be able to read the floor at a glance.

Frequently asked questions

What do the different hi-vis vest colours mean in a factory?

There is no single legal rule, so each site sets its own scheme, but common conventions are: yellow for general operatives, orange for warehouse and yard staff, red for fire wardens, green for first aiders, blue for maintenance and engineering, and unusual colours like purple or pink for visitors and new starters. The colours let staff identify each other’s roles from a distance.

Is there a standard colour for first aiders or fire wardens?

Not a legal one, but by widespread convention green (or paramedic green) is used for first aiders and red is used for fire wardens and emergency response. What matters most is that your site documents its own scheme and trains staff on it, so the colours are read consistently across every shift.

Do coloured hi-vis vests meet the EN ISO 20471 safety standard?

Only fluorescent yellow and orange (and yellow/orange combinations) reach the higher visibility classes such as Class 2. Non-standard colours like blue, red, pink and paramedic green generally rate as Class 1 or are not certified as hi-vis at all. Use them for indoor identification, but keep anyone working near forklifts or traffic in certified yellow or orange.

What is the difference between a standard hi-vis vest and an executive vest?

A standard vest is a lightweight garment focused on visibility. An executive vest is built as proper workwear, with a full-length zip, multiple pockets, a pen and phone pocket, and a sideloading ID card holder. Executive vests also come in two-tone colour designs, which keep the wearer certified while marking them out as a supervisor or manager.

Why are executive vests two colours?

The two-tone design does two jobs at once. A hi-vis yellow or orange top half keeps the wearer visible and certified, while the contrasting lower panel in navy, black, grey or royal blue instantly signals a management or supervisory role. It combines conspicuity and role recognition in a single garment.

Should factory supervisors wear yellow or orange executive vests?

A common approach is to mirror the colour their team wears. Production supervisors working on a yellow-based floor suit a yellow two-tone vest, while yard, logistics and goods-in supervisors suit an orange two-tone to match their teams. Keeping the manager’s colour in the same family as the team’s makes the hierarchy easy to read.

Can hi-vis vests be printed with roles or a company logo?

Yes. Adding text such as “FIRST AID”, “FIRE WARDEN”, “SUPERVISOR” or “VISITOR”, or your company logo, turns a colour-coded vest into a full identification system and reinforces the scheme for anyone still learning it. Every vest in our range can be printed or embroidered in-house, from a single vest to a full-site order.
