Green is the color between blue and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495–570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and blue, or yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content.
During post-classical and early modern Europe, green was the color commonly associated with wealth, merchants, bankers and the gentry, while red was reserved for the nobility. For this reason, the costume of the Mona Lisa by Leonardo da Vinci and the benches in the British House of Commons are green while those in the House of Lords are red.

Amman (English:; Arabic: عَمّان ʻammān pronounced [ʕamːaːn]) is the capital and largest city of Jordan and the country's economic, cultural and political centre. With a population of 4,007,526, Amman is the biggest city in the Levant area and the sixth-largest town in the Arab world.The earliest evidence of settlement in Amman is in a Neolithic site known as'Ain Ghazal, where some of the oldest human statues ever discovered dating to 7250 BC were uncovered. During the Iron Age, the city was known as Ammon, home to the Kingdom of the Ammonites. It was called Philadelphia during its Greek and Roman periods, and was finally called Amman during the Islamic period. For much of the middle and early Islamic periods (7th--14th centuries), it served as a centre for the Balqa district of Syria. Afterwards, Amman was a largely abandoned site before the late 19th century when Circassian immigrants were settled there by the Ottoman Empire in 1878. The first municipal council was established in 1909. Amman witnessed rapid growth after its designation as Transjordan's capital in 1921, and after several successive waves of refugees: Palestinians in 1948 and 1967; Iraqis in 1990 and 2003; and Syrians since 2011. It was originally built on seven hills but now spans over 19 hills combining 22 areas, which are administered by the Greater Amman Municipality headed by its mayor Yousef Shawarbeh.
