Colour vision
Most children who confuse colours muddle red and green, and very few see the world in grey. This topic explains, in plain words, how I test a child's colour vision with dot patterns, what the result means, and what it changes day to day at school and at home. If you have been told your child may be colour blind, start here.

Colour blindness in children: how we test for it
Usually not "everything is grey", and not something you did. How we test a child's colour vision, why it runs in families the way it does, and what a result changes in an ordinary school day.
Key takeaways
- Most people who are colour blind see partial colour, not a grey world. The usual pattern is confusing shades of red and green, and everything else looks normal.
- It is inherited on the X chromosome, so it is far more common in boys, and a mother did nothing to cause it.
- A simple book of coloured dot patterns can check for it, and a child only needs to be willing to say what he sees in the dots.
