82nd & Fifth: SEA CHANGE by Barbara Weinberg

In this rich seascape, Winslow Homer incorporates not only aquamarine blue, but also dark yellows, purples, mauves, lavenders, oranges, and golds. "The sea is a universal realm, and it's a place that we don't really understand," says curator Barbara Weinberg.

Homer reworked "Northeaster" some time between 1896 and 1901. Compare the illustration of the painting on the left, which appeared in "Harper's Weekly" in 1896, with the final version on the right.
