Abstract:
"1 don't care so much whether my color is exactly
the same, as long as it looks beautiful on my
canvas, as beautJful as it does in nature."
--Van Gogh [7]
Until the advent of impressionism, a painting's
canvas was supposed to be a featureless
window inca another world, a world that
appears just like nature.The art salons of the
time ridiculed impressionism, both because
they deemed impressionism's themes (people
in parks, a pair of shoes in the corner) trivial,
and because the painting style did not reflect
reality.This new style differed from photorealistic
painting in that the canvas wa~ no longer
invisible. Instead, the texture of the layers of
paint on the canvas was an inherent part of
the art_ Artists did not faithfully replicate the
colors of nature, they exaggerated them

(sometimes, as in Fauvism, to an extreme
degree).
