This document discusses the Color, Font, and ImageIcon classes in Java. It describes how to create and manipulate Color objects by specifying red, green, and blue values or using predefined colors. It also outlines how to select colors using the JColorChooser class. Font objects can be created by specifying a name, style, and size. Finally, ImageIcon objects can be constructed from files or URLs to display images in a program.
