Final answer:
Helen Frankenthaler's painting Mountains and Sea is a reconciliation between gesture and color-field Abstract Expressionism.
Step-by-step explanation:
Helen Frankenthaler's painting Mountains and Sea is considered a reconciliation between gesture and color-field Abstract Expressionism. In this innovative abstract painting, Frankenthaler used a large canvas laid on the floor and applied thinned paint in layers, creating a soak-stain effect. By working from all sides of the canvas, she was able to float different colors and give the painting a translucent appearance. This painting represents her unique approach to combining gesture and color-field elements in Abstract Expressionism.
