An incomplete taxonomy of self-assigned color specialties

Every discipline in science or professional practice can be sub-divided into specialties and subspecialties. E.g., in medicine a doctor could indicate that their specialty is ophthalmology and their sub-specialty the retina, or in chemistry a specialty could be analytical chemistry and a sub-specialty spectroscopy. But, what are the specialties and sub-specialties of the color discipline? The present report shares the anonymized results of a 152-participant, online survey conducted between 23rd May and 8th June 2022 that suggests 11 top-level color specialties.
