Living with Colour Vision Deficiency

Colour blind people face many difficulties in everyday life which normally sighted people are just not aware of. Problems can arise in even the most simple of activities including choosing and preparing food, gardening, sport, driving a car and selecting clothing. Colour blind people can also find themselves in trouble because they haven’t been able to pick up a change in someone’s mood by a change in colour of their face, or not noticed their child getting sunburnt.

Here are a few examples of typical problems:-

Most red/green colour blind people won’t know if they have cooked a piece of meat rare or well done and they are unlikely to be able to tell the difference between green and ripe tomatoes or between ketchup and chocolate sauce.

Colour blind people often try to eat unripe bananas because they can’t tell the difference between a green unripe banana and a yellow ripe banana – to them because both of the colours are the same shade they think they are the same colour.

Normal Vision


Some food can look repulsive if you are colour blind, and colour blind children can seem particularly fussy over green vegetables – spinach can look like cow pat and colour blind children probably mean it if they say their food looks like poo!

Colour blind people can get quite cross with electrical goods which have red and green LED displays to indicate either that a battery needs charging or the machine is on standby. An example might be a handheld games console with an indicator light which changes from red to green depending upon whether the unit is fully charged or needs recharging. This can be very frustrating, particularly for a child.

Normal Vision


In the UK colour blindness is not considered to be a disability, but in other cultures colour blindness is regarded as a defect. In Japan, for example, colour blind people are excluded from a number of careers and in many communist countries colour blind people are not permitted to drive because they are not always able to read coloured lights correctly.

Relatively little research has been done into the effects of colour blindness in everyday life. This is because until now the general population has been unaware of the difficulties that colour blindness can cause on a daily basis. UK society has therefore on the whole treated colour blind people no differently to people with normal colour vision. Colour blind people learn to manage quite well but this does not mean that their needs can be ignored.

The Colour Blind Awareness organisation aims to increase awareness of the needs of colour blind people in everyday life. Some areas of industry, transport services and the armed forces are probably the only areas where it is accepted that colour blindness could potentially cause problems and it is recognised that there are certain types of job which the colour blind are not suited to. Industry is also forced by legislation to account for colour blind people in the workplace but only for safety reasons.

Sadly most business people don’t take account of whether all of their target audience can read or understand most of the documents or presentations which they produce.

Amazingly hardly any businesses have yet to realise that they may be missing out on about 5% of their target markets because they are not aware of the effects of colour blindness. See the business section for further details.

By far the most important oversight is the plight of colour blind school children who are left to struggle in the classroom due to lack of awareness of the effects of their disability by both their parents and teachers. Even the UK Government does not currently support colour blind children in schools because in its opinion colour blindness is not a Special Educational Need. Teachers are not given any training on the issue of colour blindness or upon how to treat colour blind children in a school environment.

Colour blindness will also affect which careers can be pursued and colour blind school leavers are not usually given careers advice which includes information about which careers they may find it difficult or impossible to follow.
