Lauren is mostly a feminine given name. The name's meaning may be "laurel tree", "sweet of honor", or "wisdom". It is derived from the French name Laurence, a feminine version of Laurent, which is in turn derived from the Roman surname Laurentius.

Although originally a male name, the name's popularity with females has been widely attributed to actress Lauren Bacall (born Betty Joan Perske). It is a popular name in the United Kingdom, the United States, and Australia. In the U.S. the name ranked #170 in 2018 and #148 in 2017. The name was most popular in the U.S. in the 1980s and 1990s.

Polo is a ball game that is played on horseback as a traditional field sport. It is one of the world's oldest known team sports, having been adopted in the Western world from the game of Chovgan (Persian: چوگان), which originated in ancient Iran, dating back over 2,000 years. Initially played by Persian nobility as a training exercise for cavalry units, polo eventually spread to other parts of the world. The game is played by two opposing teams with the objective of scoring using a long-handled wooden mallet to hit a small hard ball through the opposing team's goal. Each team has four mounted riders, and the game usually lasts one to two hours, divided into periods called chukkas or chukkers.

Polo has been called "the sport of kings" and has become a spectator sport for equestrians and high society, often supported by sponsorship. The progenitor of polo and its variants existed from the 6th century BC to the 1st century AD, as an equestrian game played by the Iranian peoples. From Iran, where the sport evolved and developed, the game became popular around the world, with well over 100 member countries in the Federation of International Polo, and is played professionally in 16 countries; it was also an Olympic sport from 1900 to 1936.

Arena polo is an indoor or semi-outdoor variant with similar rules, and is played with three riders per team. The playing field is smaller, enclosed and usually of compacted sand or fine aggregate. Arena polo has more maneuvering due to space limitations, and uses an air-inflated ball slightly larger than the hard solid ball used in field polo. Standard mallets are used, though slightly larger-head arena mallets are an option.

Red is the color at the long wavelength end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and a secondary color (made from magenta and yellow) in the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy.

Red pigment made from ochre was one of the first colors used in prehistoric art. The Ancient Egyptians and Mayans colored their faces red in ceremonies; Roman generals had their bodies colored red to celebrate victories. It was also an important color in China, where it was used to color early pottery and later the gates and walls of palaces.^: 60–61 In the Renaissance, the brilliant red costumes for the nobility and wealthy were dyed with kermes and cochineal. The 19th century brought the introduction of the first synthetic red dyes, which replaced the traditional dyes. Red became a symbolic color of communism and socialism; Soviet Russia adopted a red flag following the Bolshevik Revolution in 1917. The Soviet red banner would subsequently be used throughout the entire history of the Soviet Union. China adopted its own red flag following the Chinese Communist Revolution. A red flag was also adopted by North Vietnam in 1954, and by all of Vietnam in 1975.

Since red is the color of blood, it has historically been associated with sacrifice, danger, and courage. Modern surveys in Europe and the United States show red is also the color most commonly associated with heat, activity, passion, sexuality, anger, love, and joy. In China, India, and many other Asian countries it is the color symbolizing happiness and good fortune.^: 39–63
