Final answer:
The Rococo art movement began in 18th century France contrasting the Baroque style. While Rococo painting featured pastel colors and light themes, it did not start by imitating Poussin, Giotto, Rembrandt, or Rubens. Nicolas Poussin's style influenced the later Neoclassical movement, not the Rococo.
Step-by-step explanation:
The Rococo art movement began as a reaction against the Baroque style, with its origins traceable to early 18th century France. Renowned for its light-hearted depiction of aristocratic life, the Rococo style employed pastel colors, asymmetrical forms, and playfully elegant themes. While Rococo painting is characterized by a pastel-based palette and ornamentation, it was not directly inspired by the styles of Poussin, Giotto, Rembrandt, or Rubens at its inception. Instead, it developed as a unique form in itself. However, later during the period of Neoclassicism, artists such as Jacques-Louis David, Jean-Auguste-Dominique Ingres, and Paul Cézanne looked to Nicolas Poussin for inspiration, seeking to move away from Rococo's perceived decadence to a more moral, instructive form of art emphasizing clarity and order, marking him as an antithesis to Rococo.
