Why this matters
A child can love football and still be misunderstood by it.
Football uses colour everywhere: kits, bibs, cones, balls, goalkeeper shirts, referee shirts, tactical boards, apps, screens and coaching instructions. For some colour-blind players, colour is not fast enough to trust under pressure.
“The player may not be lacking ability. Their ability may be trapped behind constant doubt.”The answer is not pity. The answer is awareness, earlier testing, clearer coaching, better cues, privacy and dignity.
For Players
You are not broken.
If kits, bibs, cones or colours confuse you, that does not mean you are stupid, lazy or not good enough. You may need clearer cues that work for your vision.
For Parents
Notice the pattern early.
A wrong pass does not prove colour blindness. But repeated confusion with certain kits, cones, bibs, school colours or match conditions is worth checking properly.
For Coaches
Coach the game, not the confusion.
This is not about lowering standards. It is about making the information clear enough so the player can be judged on football, not avoidable visual confusion.
The numbers football cannot ignore
Colour blindness is not a tiny issue.
These awareness figures show why the mission matters. Colour blindness can be easy to miss, and football uses colour everywhere: kits, bibs, cones, balls, lines, goalkeeper shirts, referee shirts, screens and tactical boards.
Awareness estimates, not diagnosis
Global scale estimate
62.4M
Approximately 62.4 million children and adolescents worldwide may have congenital colour vision deficiency. This is a scale estimate, not an official count.
UK under-18 estimate
634k–636k
Approximately 634,000 to 636,000 UK under-18s may be affected. This is an author awareness estimate, not an official UK diagnosis count.
Male children
1 in 12
A commonly used rule of thumb is around 1 in 12 males, roughly 8%. Prevalence can vary by population and ancestry.
Female children
1 in 200
A commonly used rule of thumb is around 1 in 200 females, roughly 0.5%. Girls can be colour blind too.
💡 Key takeaway: UK education awareness guidance warns that approximately 80% of colour vision deficient students may be undiagnosed when they enter secondary school. That means some children may be struggling through primary-school years before anyone knows to ask about colour vision.
These figures are for awareness and should not be used to diagnose a child. A standard eyesight check and a colour vision test are not always the same thing, so parents may need to ask a qualified eye-care professional specifically about colour vision testing. Useful references: Colour Blind Awareness, Colour Blind Awareness education guidance, and 2025 paediatric systematic review/meta-analysis listing.

Before You Blame the Player
A child can train hard, listen carefully and love football deeply — and still make a mistake that looks obvious from the sideline but felt confusing inside the game.
The Moment Before the Mistake
The real story often begins before the pass. It begins when two shirts do not separate quickly, when socks are muddy, or when a bib becomes unclear at speed.
What Did You See?
This question slows the judgement down. It does not excuse every mistake. It helps adults understand the information the player had before the action happened.
Colour Is Information
Football uses colour to organise the game. Kits, bibs, cones and boards are not decoration. They tell players what to do quickly.
Free tools and resources
Free help for players, parents and coaches.
The site should not only explain the problem. It should give people something useful immediately.

Cornelius Aurelius
Author, creator and founder of the Colour Blindness in Football awareness mission.
The why behind the mission
Cornelius was the hidden player.
Cornelius Aurelius is colour blind. He dreamed of becoming a professional footballer and found out late that colour blindness had been part of the struggle.
He knows the confusion, the confidence damage, the substitutions, the wasted opportunities, the regret of not knowing earlier, and the feeling of being alone without anyone teaching him how to adapt. This project is his way of helping the next child earlier.
Support Cornelius personally
Cornelius builds these books, games, tools and awareness pages himself. Sponsorship money helps fund the football mission. A personal tip helps Cornelius keep creating useful projects, tools and resources that can help more people.
Final call
Help the next child before confidence breaks.
Colour blindness does not steal talent. Unrecognised colour blindness can steal opportunity. The answer is awareness, earlier testing, clearer coaching and better football information.
Educational awareness only. This site does not diagnose colour blindness or replace professional eye-care, medical, coaching, safeguarding or legal advice. If eyesight or colour vision is a concern, speak to a qualified eye-care professional and ask specifically about colour vision testing.
