Asher Brown Durand quotes:

All the best artists have shown that the greatest achievement in the production of fine color is the concealment of pigments, and not the parade of them; and we may say the same of execution.

Waste not your time on broad sketches in color.

Let me earnestly recommend...one studio which you may freely enter and receive in liberal measure the most sure and safe instruction...the Studio of Nature.

I would sooner look for figs on thistles than for the higher attributes of art from one whose ruling motive... is money.

The less apparent the means and manner of the artist, the more directly will his work appeal to the understanding and the feelings.
