Many teachers are not aware of the effects of colour deficiencies in young children. If teachers were made aware of the potential problems of color blindness, steps could be taken to aid the
students with these deficiencies. It is often taken for granted that all children see in colour.   
Melanie Lilliston (Lecturer U.S.A. ASU)


The main symptom of CDV is in the difficulty of distinguishing colours or making mistakes when identifying colours.
It is possible the child may just need time to learn his or her colours
but the following are some clues to look out for:-

  • Using the wrong colours for the object. (Trees etc;)
  • Using dark colours. (Black and Blues)
  • Low attention span when colouring in work sheets.
        (Loss of interest)
  • Denial of colour issues. Would rather be labelled slow etc;
  • Problems in Identifying RED OR GREEN colour pencils or any colour pencil with RED or GREEN in the composition.
  • Identification of colour may be made worse by low level light and small colour areas.
  • Some reading issues may appear on coloured pages or work sheets with colour on colour.
Some of the following clues may also be exhibited
  • Smelling food before eating.
  • Good sense of smell
  • Good night vision.
  • Sensitivity to bright lights

The symptoms are not limited to the above but give parents some likely CDV indicators. Remember it is important for the child to be checked by your Doctor and Optometrist as symptoms may be part of other conditions or health issues. (Medicines, illness, injury or some dyslectic disorders.) Contact us for Information.

One of the main problems associated with colour deficiencies is that it is very hard to detect. Many times children simply adapt to the environment and are not tested to see if they are colour-deficient. They get by with adapting to the situation, and may never realise they suffer from colour blindness. They may create their own shortcuts to maintain their problem as a secret. In a way we are our own worst enemy; thus people assume there is no problem. Parent discussion with the teachers on a child's colour perception issues should be done with the classification and variation in mind, including some input from the child. (Board Colours) Position of the student in the classroom should also be considered away from reflected light and glare and seated in front and square to the board.

Do not forget there will be some colour issues in secondary schooling  subjects such as, Chemistry, Physics, Geography, Graphs and Food Technology. Careers are another  issue that needs to be addressed not only by school counsellors but by all employers concerning prospective CDV students and employees.
