- grapheme-colour synaesthesia
- A term used to denote a type of synaesthesia in which letters or numbers are perceived as inherently coloured. Thus the A can be experienced as red, the B as green, the C as magenta, and so on. Intraindividually the associations between graphemes and colours tend to remain constant over time; interindividual constancies have never been described. The German Egyptologist Karl Lepsius (1810-1884) reportedly employed grapheme-colour synaesthesias as a guide in his philological inquiries. A woman described by the British scientist Sir Francis Galton (18221911) used hers to facilitate reading. Grapheme-colour synaesthesias can also be classified as atypeof * synaesthetic configuration. They should not be confused with * number-forms.ReferencesCytowic, R.E. (2002). Synesthesia. A union of the senses. Second edition. Cambridge, MA: MIT Press.Galton, F. (1883).
