Red, yellow, pink and… what? Karen Sullivan examines how being colour-blind can impact on a child’s education, and why screening before entering nursery can make a big difference to their wellbeing.

Key pointsl The average UK co-educational school classroom will be host to at least one
colour-blind childl In an average box of 24 coloured pencils, a child who has the most common form
of colour-blindness will be able to accurately name only four colours, although they will probably be able to guess more
l As colour-blind children are not currently supported in the classroom, from an early age and before they begin to learn to read and write, most feel inadequate, some lose confidence and struggle to cope, some are put off school and some become unwilling to learn and develop into disruptive pupils
l Most colour-blind children are unaware of their condition, many only realise they are colour-blind at secondary school. Many do not admit it
l Because a greater number of boys suffer, they are disadvantaged and lag behind girls in many subjects, including maths, science, geography, reading, sport, food technology and in any lessons where teaching uses colour as a talking point
