Vincent van Gogh's doctor's letters have been published in the British Journal of Psychiatry. Jonah Lehrer discusses here. Money quote from the doc:
Vincent was above all a miserable, wretched man ... he would talk to me about complementary colours. But I really could not understand why red should not be red, and green not green! ... When I saw that he outlined my head entirely in green (he had only two main colours, red and green), that he painted my hair and my mustache—I really did not have red hair—in a blazing red on a biting green background, I was simply horrified. What should I do with this present?Props: The Dish
