Jobs That Require a Color Vision Test

Short answer

Some safety-critical jobs set color vision standards, including aviation, rail, maritime, and certain military roles. A deficiency is not always disqualifying; requirements depend on the role and authority.

Plenty of jobs check color vision, but far fewer ban color-blind people outright. Safety-critical roles that depend on reading colored signals or wiring set a color vision standard: pilot, air traffic controller, seafarer, train driver, and some military and police posts. Most use the Ishihara test as a first screen, with a practical or lantern test as a fallback, so mild red-green deficiency often passes while strong or total color blindness is where the real limits begin. The table below gives the requirement and the official source for the most-asked occupations.

The phrase people search is usually "color vision test for the army" or "Ishihara test for seaman," but the question underneath is the same everywhere: does my color vision meet this job's standard, and what happens if it doesn't? The answer depends on the role and the country, not on one global rule. Here is what the main standards require, who can still qualify, and where to confirm it.

Color-vision requirements by job

Whether a color vision deficiency lets you hold the role. Every row links to the official standard. Rules vary by country and employer — treat this as a starting point, not the final word.

Usually OK
A color vision deficiency usually does not bar this role.
Conditional
Allowed if you pass a color check or meet a set standard; mild cases often qualify.
Restricted
Color-critical: usually only mild deficiency qualifies, often with limits.

Aviation

Airline / commercial pilot

United States (FAA)

Conditional

You can fly commercially if you pass one of the FAA-approved color vision tests; if you can't, a 3rd-class certificate is still available, restricted to day visual-flight-rules only.

As of 2025, an in-person computer test (CAD, Rabin Cone Test, or Waggoner CCVT); home or printed tests are not accepted.

FAA — Guide for Aviation Medical Examiners, Item 52As of 2025

Pilot (general standard)

International (ICAO)

Conditional

ICAO requires pilots to perceive the colors needed for safe duties but sets no fixed pass mark, so the exact threshold and any 'daytime-only' restriction are set by your national authority.

Ishihara-type plates first; a lantern or signal-light test if you fail the plates.

ICAO — Annex 1 (Aviation Medicine)As of 2026

Pilot (Class 1 / Class 2)

Europe (EASA)

Conditional

Commercial (Class 1) pilots must be 'color safe'; a private (Class 2) applicant who isn't can still fly with a daytime-only restriction.

Ishihara 24-plate (first 15 read without error to pass); an anomaloscope or lantern test as a fallback.

EASA — Part-MED, MED.B.075 (Color vision)As of 2023

Air traffic controller

United States (FAA)

Restricted

Controllers must pass color screening or the dedicated ATCOV test; failing it usually means medical disqualification unless you can be limited to non-color-critical equipment.

Color screening, then the Air Traffic Controller color vision test (ATCOV) if you fail.

FAA — Order 3930.3C (ATCS Health Program)As of 2019

Cabin crew

Europe (EASA)

Usually OK

Color vision is checked, but the role isn't treated as color-critical, so a deficiency is generally not disqualifying.

Ishihara screening; a practical, task-based check if you fail, rather than an automatic bar.

EASA — Part-MC/Part-CC cabin-crew medicalAs of 2023

Maritime & seafaring

Seafarer — deck & lookout

International (IMO STCW)

Restricted

Deck officers and lookout crew need near-normal color vision (CIE color vision standard 1 or 2) to identify navigation lights, so significant red-green deficiency usually fails.

Ishihara or equivalent per CIE 143-2001, with a lantern test as the recognized fallback; re-tested every 6 years.

IMO — STCW Code, Table A-I/9As of 2023

Seafarer — engine department

International (IMO STCW)

Conditional

Engine-department crew can qualify with a milder deficiency (up to CIE color vision standard 3), so mild-to-moderate red-green often passes.

The same Ishihara / CIE 143-2001 screen as deck crew, but with a more permissive pass threshold.

IMO — STCW Code, Table A-I/9As of 2023

Merchant mariner

United States (USCG)

Conditional

US deck endorsements need satisfactory color sense on an approved test; engine, radio and tank-vessel roles must instead distinguish red, green, blue and yellow.

Approved plates or a lantern (no color-sensing lenses); the Farnsworth D-15 is accepted for the engineering standard.

USCG — 46 CFR 10.305 (Cornell LII)As of 2026

Military & police

Armed forces entry

United States

Conditional

Color vision is screened at enlistment but isn't an automatic bar; a deficiency instead closes off specific color-critical specialties.

Ishihara / pseudo-isochromatic plates, with a cone-contrast or lantern test as the confirmatory step.

US Army — AR 40-501 (Standards of Medical Fitness)As of 2023

Armed forces entry

United Kingdom

Conditional

The UK grades color perception CP1–CP4; many trades accept CP3 (telling signal red, green and white apart), while specialist, maritime and flying roles need CP2 or CP1.

Ishihara plates, then a Holmes-Wright lantern if you fail, graded on the CP system.

UK MoD — PULHEEMS Administrative Pamphlet (PAP10)As of 2015

Armed forces entry

India

Conditional

India grades color perception CP-I to CP-IV; flying branches require CP-I, while many Army ground roles accept CP-III (recognizing signal red, green and white), so mild deficiency can still serve.

Ishihara and Tokyo Medical College plates, then the Martin lantern test for grading.

Indian Journal of Aerospace Medicine (CP grading)As of 2012

Police officer

United Kingdom

Usually OK

Most color-deficient applicants are accepted, including dichromats, who are taught coping strategies; only complete color blindness (monochromacy) is rejected.

Farnsworth D-15 test (color-correcting lenses are not allowed).

UK Home Office — Police Eyesight Standards (Reg 10)As of 2014

Police officer

United States

Conditional

There's no national standard: many states leave color vision to the hiring agency, while others (e.g. Michigan) require normal color vision and don't accept color-correcting lenses.

Ishihara plates, with the Farnsworth D-15 for anyone who fails (varies by state and department).

Michigan MCOLES — Police Color Vision StandardAs of 2022

Rail & road

Locomotive engineer

United States

Conditional

Engineers must recognize railroad signal colors; failing the plate test isn't an automatic bar, since the examiner can use practical testing and may certify you with restrictions such as no night operation.

Pseudo-isochromatic plates or a vision tester from the FRA's approved list (Appendix F).

FRA — 49 CFR 240.121 & Appendix F (Cornell LII)As of 2026

Train driver

United Kingdom

Conditional

Drivers need adequate color vision; a revised protocol now sends anyone who fails Ishihara to a CAD test, so roughly half of those who fail the plates can still be assessed as safe.

Ishihara (zero errors to pass), followed by the CAD test to grade severity.

RSSB — standard RIS-3789-TOMAs of 2025

Commercial driver (CDL)

United States

Conditional

A commercial driver must be able to recognize red, green and amber traffic-signal colors; it's a functional check, so many people with mild deficiency still qualify.

Color recognition during the DOT medical exam, not a strict Ishihara cutoff.

FMCSA — 49 CFR 391.41(b)(10) (Cornell LII)As of 2026

Trades & emergency services

Electrician / electrical trades

United States

Usually OK

There's no federal color vision standard; OSHA states it requires none, so any test is set by an apprenticeship or employer rather than the law.

None mandated; some apprenticeship or union entry physicals add their own check, the rationale being color-coded wiring.

OSHA — Standard Interpretation (no color-vision rule)As of 2004

Firefighter

United States

Conditional

NFPA 1582 treats total color blindness that blocks essential tasks (such as using thermal-imaging devices) as potentially disqualifying, while ordinary red-green deficiency is judged case-by-case against the job's essential tasks.

Medical evaluation against essential-job-task criteria, rather than a single plate cutoff.

NFPA 1582 (Fire Dept. Medical Program)As of 2022

Last reviewed June 14, 2026. Standards change and many roles are governed locally — always confirm the current requirement with the relevant authority or employer. Informational only, not legal or medical advice.

What workplace color-vision standards actually check

Almost every occupational standard is really asking one thing: can you tell apart the specific colored signals the job depends on, such as navigation lights, railway signals, or color-coded wiring. That is why the Ishihara test is only the first step. Fail it and the better standards send you to a practical check (a lantern, a signal-recognition test, or the CAD test) that measures the real-world task instead of a printed plate. The result is that a mild red-green deficiency clears many standards, while a strong one or total color blindness is where roles start to close.

A note on Philippine seafarers and the PNP

Two of the most-searched cases are Filipino. For seafarers, the standard above is the international STCW one your flag state enforces, so the deck-versus-engine split is what matters most. For the Philippine National Police, the Ishihara test is part of the recruitment medical, but we have not been able to verify the exact current pass rule from an official NAPOLCOM or PNP document, so it is left out of the table above rather than guessed. Confirm the current standard directly with the recruiting authority.

Check where you stand first

Before a job medical, it helps to know your type and severity. Take the color vision test for an estimate across all three cone types, or the Ishihara test for a quick red-green screen.

Color vision at work — frequently asked questions

What jobs can't you do if you're color blind?
The firm limits cluster around color-critical safety roles: an unrestricted commercial pilot, an air traffic controller, a deck officer at sea, and certain military flying and specialist posts. Even there, mild deficiency often passes and restricted pathways exist (for example, a daytime-only flying certificate). Total color blindness is the most limiting, but it is also very rare.
Can you be a pilot if you're color blind?
Often, yes, with conditions. The FAA, EASA and ICAO frameworks let you fly if you pass an approved color vision test or a practical signal-recognition assessment. If you can't pass, you may still hold a restricted certificate, such as day visual-flight-rules only or a private-pilot license, rather than being grounded entirely. The strictest bar is on unrestricted commercial flying and on air traffic control.
What is the color vision test for the army?
Militaries grade color perception rather than giving a simple pass or fail. The UK uses CP1–CP4 and India uses CP-I to CP-IV, both starting with Ishihara plates and adding a lantern test. Flying branches need the top grade, but many ground roles accept a lower one (for example, the UK's CP3 or India's CP-III, which only require telling signal red, green and white apart), so a mild deficiency can still serve.
Do you need normal color vision to be a seafarer?
It depends on your department. Under the international STCW standard, deck officers and lookout crew need near-normal color vision (CIE color vision standard 1 or 2) to read navigation lights, so significant red-green deficiency usually fails. Engine-department crew can pass with a milder deficiency (up to CIE standard 3). The Ishihara test is the usual screen, with a lantern test as backup, and color vision is re-checked every six years.
Will color blind glasses help me pass a job color vision test?
No. These tests are taken without aids, and color-correcting lenses are explicitly not allowed for aviation, maritime, rail and police standards. The lenses also shift colors rather than restore accurate ones, so they can't make your color vision count as normal for an occupational standard.
How do I know if I'll qualify?
Take a screening first to learn your type and severity, then match that against the standard for the role you want. A mild red-green deficiency clears many of these standards; a strong one narrows the options. For anything official, confirm the result with an approved examiner using the test your employer or licensing body specifies.
