Mark Rothko, No. 2 (No. 7 and No. 20),1951 (alternatively dated to 1950), Collection of Mrs. Paul Mellon, Upperville, Virginia
Now applied in thin washes (often composed of both oil and egg-based
media), Rothko's color achieved a new luminosity. The artist's technique appears
simple, but on close examination is richly varied in its range
of effects. At times, paint can be seen running upward across
the surface; this is because Rothko often inverted a picture
while working on it, sometimes changing the final orientation
at a late stage.
