Helen Frankenthaler's *Autumn Series* showcases her signature soak-stain technique, with luminous washes of acrylic color flowing organically across C.M. Fabriano paper. The fluid, translucent layers evoke the shifting hues and ephemeral beauty of the autumn season, blurring the boundaries between control and chance. Frankenthaler's intuitive mark-making transforms the absorbent paper into a dynamic field of color and movement, reflecting her pivotal role in the development of Color Field painting.
