Green is a color made by combining yellow and blue pigment. It is a primary color in light. Green is the color of many plants and other organisms, due to the presence of chlorophyll.

In the poem "Nothing Gold Can Stay", Robert Frost wrote:

Nature's first green is gold, her hardest hue to hold.[1]

Green is also a term used to refer to environmentally friendly products and services, such as hydroelectric energy from dams, or paper towels made from recycled paper products. Green sources of power are seen as a method of securing energy independence for the United States, and as a way of protecting the environment from the negative impacts of burning fossil fuels.

The color green corresponds to wavelengths of 520 nanometers to 565 nanometers in the electromagnetic spectrum.[2]
