Male: A stain is made
when you take a paint and you thin it out with a lot of solvent. In the case of oil painting,
a lot of turpentine. The paint becomes very, very watery. It becomes very dilute. The color is reduced, and also because it's so watery that stain
can actually penetrate into the canvas itself. In the work of Rothko
we know that he layered stain over, stain, over stain. We're quite literally
seeing through these very, very thin washes, if you will, of paint.
