Following Quotes - page 18
The new discovery that I have made in painting is the following. There are chords of colors, let's say a certain red and green, which move, shimmer when you look at them. Now if you're looking at a tree in a landscape, you can either look at the tree, or at the landscape, but not both, because of the stereoscopic effect. Now, when you are painting something three-dimensional, the chromatic sound which shimmers is the three-dimensional effect of colour, and when you paint a landscape, and the green foliage shimmers a little with the blue sky showing through it, that happens because the green is on a different plane from the sky in nature too. Finding the space-shaping energies of colour, instead of contenting ourselves with a dead chiaroascuro, is our finest task.
August Macke
