"One would have to coin a word for the occasion if one wished to characterise the talent of Gustave Moreau, the word colourism for example, which would well convey all that is excessive, superb and prodigious in his love for colour.. .It is as if one were in the presence of an illuminator who had been a jeweler before becoming a painter and who, having yielded to the intoxication of colour, had ground rubies, sapphires, emeralds, topazes, opals, pearls and mother of pearl to make up his palette."
