<human>:  Help me compare and contrast classical and modern art.
<bot>: Classical art is defined as art that is produced in the period between the Ancient Greece and Rome with the fall of the Roman Empire. It defines an era of painting, sculpting, architecture and other forms of artistic expression that had a major influence on later art and culture. Characteristic of classical art is the use of realistic depictions of naturalistic subjects such as gods, heroes, and everyday people. Colors used in paintings were usually muted to represent the solemn will of the ancient gods.2 Modern art on the other hand, is art that has been created from the late 19th century onwards. It challenges conventional approaches to creating art and has been evolving since the dawn of the 20th century. Modern art utilizes a range of materials, styles and media. Rather than attempting to imitate nature, modern art often expresses emotion, experiences, or political and social issues. Its color palette is much broader than classical art and includes bright, bold colors that create unique, often abstract compositions.
