Abstract
In the seventeenth century, Newton used bis famous prism to found the physics of spectral light, thus revolutionising our thinking about colours; more than a hundred years later, Goethe protested against Newton's theory and discovered a number of new prismatic colour phenomena. Did these episodes in the history of science have any influence on the visual arts? For a decade now my visits to art museums have had an agenda: I have been looking for nineteenth-century paintings with certain spectral colour (which will be described in the first half of this paper). While my search has been unsuccessful in traditional Western art, I found what I was looking for in Japanese art: in woodblock prints by Hokusai and Hiroshige. This is surprising; little Western science had reached Japan in their time. The second half of the paper presents this riddle, which I am nowhere near solving. Even without a solution, however, a riddle can be instructive. In this case, it may help to bring into focus the fascinating exchange between two distant cultures. Much has been written on the cultural relativity of colour perception, colour systematisation and colour aesthetics; I want to introduce a new and so far unknown case that might contribute to this debate - though the debate itself remains beyond the scope of this paper.
