Adapting sorting exercises for those with Limited Colour Vision
You may have students in your class who do not have full colour vision. They may have limited colour vision or ‘colour vision deficiency’ – those terms are preferred to the more common term ‘colour blindness’(which may incorrectly infer that a person does not see colour at all). Limited colour vision can vary in type and severity. Those with limited colour vision will most likely not be able to distinguish all 45 tiles in the sorting set and will instead see some of these as having the same colour. The sorting exercises can be adapted for each student’s chromatic palette.
Free Sort and Separating Chromatic from Achromatic Colours can be done without modifications. You may find that these students see more achromatic or muted colours, depending on the type and severity of their limited colour vision.
Arranging Coloured Tiles in Hue Families can be done with the hues these students are able to distinguish. Have the students first sort the chromatic from the achromatic colours, and work with the subset of coloured tiles that they can distinguish. Some tiles may appear as the same colour to these students; the tiles that appear the same or similar will depend on the type and severity of their limited colour vision.
Arranging Coloured Tiles in Groups of the Same Character can likely be done without modifications, although the students may find the pale and muted versions of some hues to appear the same or similar.
Spacing Between Hue Families may be performed after first removing the tiles they see as achromatic from their set. Depending on the type and severity of their limited colour vision, the student may arrange the tiles with different spacings from those with full colour vision.
For the Lightness/value and Chroma exercise, after establishing the greyscale with achromatic colours, the student may prefer to work with all the remaining tiles and sort by lightness/value, and omit the sorting by chroma.
The Arranging Coloured Tiles in Hue Sequence exercise may be performed after first removing the tiles they see as achromatic from their set.
