Green is any of a number of similar colors. Green is seen commonly in nature, especially in plants. Many plants are green mainly because of a complex chemical known as chlorophyll which is involved in photosynthesis.

Green light has a wavelength of roughly 520–570 nm and is considered one of the additive primary colors. It is the complement of magenta; more properly the color #FF00FF. People who are red-green color blind can often distinguish between the two colors but confuse them with other colors, for example, bright green with yellow; dark green with brown.

The term "green" does not define an exact color unless it is conjunction with some standard like X11 colors or an absolute color space like sRGB. The two colors shown to the right are wildly different, but each is called "Green" in a widely used color standard.
