In comparison to baroque art, the style of rococo:

The style of Rococo is much lighter, both in topics and style. While Baroque dealt with obscure subjects in a passionate way (for example, Caravaggio's street brawls, alcoholism, lunacy, terrifying Medusa with the artist's own face), and had heavily ornamented style in architecture and music, Rococo artists had an inclination toward pastoral scenes with shepherds or mythological figures, family life or members of the upper classes. So, Rococo paintings were optimistic, idyllic, shallow, devoid of dark undertones.
