Two things combined this morning: a reported conversation between Gauguin and Sérusier, and the painting posted by Susan Abbott on March 7.
The conversation ran like this:
Gauguin: How to you see the colour of that tree?
Gauguin: Well, use your very best yellow. How do you see the colour of the earth?
Gauguin: Then use your very best red.
This bit was on p. 193 of Ball's Bright Earth, still my nightly read.
There's a lot to chew on in these few lines: about color, and about how to make art.
