>For other uses, see Green (disambiguation). Green is a color seen commonly in nature. 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 one of the additive primary colors. It is the complement of magenta. Many artists, however, continue to use a traditional color theory in which the complement of green is considered to be red.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.

>For other uses, see Summer (disambiguation). Summer is a season, defined by convention in meteorology as the whole months of June, July, and August, in the Northern hemisphere, and the whole months of December, January, and February, in the Southern hemisphere. In some Western countries, the first day of summer (in the Northern hemisphere) falls either on, or around, June 21 or on June 1 (the former is the astronomical start; the latter, the meteorological). Summer is commonly viewed as the season with the longest (and warmest) days of the year, in which the daylight predominates, through varying degrees. In the northern latitudes, twilight is known to last at least an hour, sometimes leading to the famous white nights found in St. Petersburg and Scandinavia. See more at Wikipedia.org...
