Color Task
Color tasks are tasks that involve the recognition of Color, colors. Color tasks can be classified according to how the color is interpreted. Cole 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. In Cole's definitions, the latter would be denotative color tasks and the others would be comparative color tasks.

Color (or colour in English in the Commonwealth of Nations, Commonwealth English; American and British English spelling differences#-our, -or, see spelling differences) is the visual perception based on the electromagnetic spectrum. Though color is not an inherent property of matter, color perception is related to an object's light absorption, emission spectra, emission, Reflection (physics), reflection and Transmittance, transmission. For most humans, colors are perceived in the visible light spectrum with three types of cone cells (trichromacy). Other animals may have a different number of cone cell types or have eyes sensitive to different wavelengths, such as bees that can distinguish ultraviolet, and thus have a different color sensitivity range. Animal perception of color originates from different light wavelength or spectral sensitivity in cone cell types, which is then processed by the brain. Colors have perceived properties such as hue, colorfulness (saturation), and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
