- problems in identifying ripe fruits and vegetable
- pencil with red or green in its composition. (e.g.purple, brown).
- identification of colour may be made worse by low level light, small areas of colour and colours of the same hue.
- problems in identifying colour of food preparing.
- problems in identifying lights in night.
- sensitivity to bright lights.
- reading issues with coloured pages or worksheets produced with colour on colour.
- children may complain that their eyes or head hurt, if looking at something red on a green background, or vice versa.
