What is meant by the pearly period in Pierre-Auguste Renoir’s painting?

The term "pearly" period refers to a phase in Pierre-Auguste Renoir’s career, occurring around the early 1890s, characterized by a shift in his artistic technique. During this time, Renoir moved away from the linear, disciplined drawing style he had adopted during his "harsh" or "Ingres" period (roughly 1883–1890) and returned to a more fluid, feathery brushstroke.12

This period is noted for its luminous quality and the use of a pastel-heavy palette, which allowed him to capture the soft, intimate atmosphere of bourgeois domestic life. Works from this era, such as Young Girls at the Piano (1892), exemplify this approach, where the artist successfully balanced his earlier experiments with Impressionism with a renewed sense of form and color.12
