Color tasks are tasks that involve the recognition of colors. Color tasks can be classified according to how the color is interpreted. Cole[1] describes four categories of color tasks:
- Comparative – When multiple colors must be compared, such as with mixing paint
- Connotative – When colors are given an implicit meaning, such as red = stop
- Denotative – When identifying colors, for example by name, such as “where is the yellow ball?”
- Aesthetic – When colors look nice – or convey an emotional response – but don’t carry explicit meaning
Earlier classification of color tasks did not attempt to be comprehensive, and mainly differentiated between color matching/ordering, pseudoisochromatic plates and color-naming.[2][3] In Cole's definitions, the latter would be denotative color tasks and the others would be comparative color tasks.
