Welcome to the Colour Blind Awareness site

The Colour Blind Awareness organisation has been founded to raise awareness of colour blindness (colour vision deficiency) and aims to be the first point of reference for in the UK for people seeking information on colour blindness.

The organisation provides support for colour blind people, especially colour blind children and their families and teachers. Advice for professionals working with the colour blind or providing services for them, can be found in the Business section.

This website provides information on the everyday problems experienced by colour blind people and offers advice to parents and carers in how to provide support for the colour blind children in their care, including details of how to access tests for colour blindness or to arrange for a formal diagnosis.

Information is provided to allow teachers to give adequate support to colour blind students in the classroom, on the sports field and in formal examinations.
