Leveling by Helen Frankenthaler (1973)

A pale horizon line floats across the canvas in Leveling, one of Helen Frankenthaler's most serene works. The painting seems to dissolve into the air, its edges barely contained by the picture plane. Below the horizon, a wash of pale blue and green stretches across the composition. The colors are thin, almost translucent, allowing the texture of the canvas to peek through. Above, a band of pale lavender suggests a sky, its soft hue barely distinguishable from the lower register. This poster suits a quiet corner, where its subtle palette can be appreciated up close.
