Joan Miro, "Prades"

Joan Miró, "Prades, The Village," 1917; The Solomon R. Guggenheim Museum.

Someone decided to change all the colors in this early Miro, resulting in the modern reproduction below. Sometimes art vendors cater to a contemporary market by brightening photos of older paintings that might have become faded over time. But that doesn't seem to be the motivation here, since the original is popping with colorful hues. Another issue is that, although Miro's painting is somewhat abstract, it still retains a sense of the natural environment, with blue sky and greenery among the more angular forms. The reproduction has turned everything purple and yellow, without regard to the natural scene.
