Sound-color synesthetes perceive distinctive colored shapes (photisms) when listening to specific tones. We presented the octave illusion to sound-color synesthetes reasoning that their photisms might prevent the illusion. The synesthetes experienced the illusion similarly to controls, suggesting that the integration of auditory stimuli occurs before the production of the photisms.
