Jim Dine is an American pop artist known for his series of paintings and sculptures featuring hearts. In his Pop Art hearts series, Dine uses the heart symbol and varies elements like color, lines, texture, and dimensionality to make each heart unique. He often uses color contrast schemes of warm and cool colors opposite each other on the color wheel. The document provides examples of Dine's heart art and discusses objectives for students to learn about pop art, creating patterns, expressing personality through color, and developing their own heart composition using different materials and styles.
