Answer: Green materials are those high in nitrogen, such as freshly mowed lawn. You can also compost kitchen scraps (nothing with grease or high in fat). You can use virtually anything else for your compost, including dried grass, green or brown leaves, even newspaper. Just try to have a mixture of different materials and your compost should be just fine. It's not an exact science, just a way to reduce the materials you send to the landfill.
Best wishes with your compost adventure!
