Speaking of l’audition colorée, the
French structuralist Gerard Genette in one of his essays quotes a book by Paul
Delbouille, POÉSIE ET SONORITÉS (1961): « Toutes les
couleurs ont au moins été attribuées une fois à
chacune des voyelles ». This probably means that VN’s
synaesthesia (the way different sounds related to different colors) was as
unique as his handwriting or fingerprints. We know that the colors of
VN’s vowels were not the same as the colors of Rimbaud’s voyelles,
which might have been equally unique.
