Colo has several meanings:
Colorado (i/kɒləˈrædoʊ/, or /kɒləˈrɑːdoʊ/) (Spanish for "ruddy") is a state in the United States encompassing most of the Southern Rocky Mountains as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. Colorado is part of the Western United States, the Southwestern United States, and the Mountain States. Colorado is the 8th most extensive and the 22nd most populous of the 50 United States. The United States Census Bureau estimates that the population of Colorado was 5,456,574 on July 1, 2015, an increase of 8.50% since the 2010 United States Census.
The state was named for the Colorado River, which Spanish travelers named the Río Colorado for the ruddy (Spanish: colorado) silt the river carried from the mountains. The Territory of Colorado was organized on February 28, 1861, and on August 1, 1876, U.S. President Ulysses S. Grant signed Proclamation 230 admitting Colorado to the Union as the 38th state. Colorado is nicknamed the "Centennial State" because it became a state 28 days after the centennial of the United States Declaration of Independence.
Colo (born December 22, 1956) is a western gorilla widely known as the first gorilla to be born in captivity anywhere in the world and as the oldest gorilla in captivity in the world. Colo was born at the Columbus Zoo and Aquarium to Millie Christina (mother) and Baron Macombo (father). She was briefly called Cuddles before a contest was held to officially name her. The contest was won by a Columbus native, Rita Cochren. Colo's name is derived from the place of her birth, Columbus, Ohio.
Colo's mother rejected her at birth, and she was hand-raised by the zookeepers like a human child, dressed in clothing and fed from a bottle. When she was two she was introduced to Bongo, a 19-month-old male from Africa, and on February 1, 1968, their first of three offspring was born, a female named Emmy, named by the zoo after the mayor of Columbus, M. E. "Jack" Sensenbrenner. The following two offspring were similarly named after awards; Oscar, born July 18, 1969, and Toni, on December 28, 1971.
