Black is the color of objects that do not emit or reflect light in any part of the visible spectrum; they absorb all such frequencies of light. Although black is sometimes described as an "achromatic", or hueless, color, in practice it can be considered a color, as in expressions like "black cat" or "black paint".

The word black comes from Old English blæc ("black, dark", also, "ink"), from Proto-Germanic *blakkaz ("burned"), from Proto-Indo-European *bhleg- ("to burn, gleam, shine, flash"), from base *bhel- ("to shine"), related to Old Saxon blak ("ink"), Old High German blah ("black"), Old Norse blakkr ("dark"), Dutch blaken ("to burn"), and Swedish bläck ("ink"). More distant cognates include Latin flagrare ("to blaze, glow, burn"), and Ancient Greek phlegein ("to burn, scorch"). Black supplanted the wonted Old English word sweart ("black, dark"), which survives as swart, swarth, and swarthy (compare German schwarz and Dutch zwart, "black").

Black can be defined as the visual impression experienced when no visible light reaches the eye. (This makes a contrast with whiteness, the impression of any combination of colors of light that equally stimulates all three types of color-sensitive visual receptors.)

Donald Jay "Don" Rickles (born May 8, 1926) is an American stand-up comedian and actor. A frequent guest on The Tonight Show Starring Johnny Carson, Rickles has acted in comedic and dramatic roles, but is best known as an insult comic.

Rickles was born in the New York City borough of Queens to Max Rickles, who had emigrated in 1902 with his parents Joseph and Frances Rickles from Kaunas, Lithuania (then in the Russian Empire), and Etta (Feldman) Rickles, born in New York to immigrant parents from the Austrian Empire. His family was Jewish and spoke Yiddish at home. Rickles grew up in the Jackson Heights area.

After graduating from Newtown High School, Rickles enlisted in the U.S. Navy and served during World War II on the USS Cyrene as a seaman first class. He was honorably discharged in 1946. Two years later, he studied at the American Academy of Dramatic Arts and then played bit parts on television. Frustrated by a lack of acting work, Rickles began doing stand-up comedy. He became known as an insult comedian by responding to his hecklers. The audience enjoyed these insults more than his prepared material, and he incorporated them into his act. When he began his career in the early 1950s he started calling ill-mannered members of the audience a "hockey puck". His style was similar to an older insult comic, "Mr. Warmth" Jack E. Leonard, though Rickles denies that Leonard influenced his style.

John William "Johnny" Carson (October 23, 1925 – January 23, 2005) was an American television host and comedian, known for thirty years as host of The Tonight Show Starring Johnny Carson (1962–1992). Carson received six Emmy Awards, the Governor Award, and a 1985 Peabody Award. He was inducted into the Television Academy Hall of Fame in 1987. Johnny Carson was awarded the Presidential Medal of Freedom in 1992 and received a Kennedy Center Honor in 1993.

Although his show was already successful by the end of the 1960s, during the 1970s Carson became an American icon and remained so until his retirement in 1992. He adopted a casual, conversational approach with extensive interaction with guests, an approach pioneered by Arthur Godfrey and previous Tonight Show hosts Steve Allen and Jack Paar. Late night hosts David Letterman, Jay Leno, Conan O'Brien, Craig Ferguson, and Jimmy Fallon have all cited Carson's influence on their late-night talk shows, which resemble his in format and tone.

Carson was born in Corning, Iowa, in the year 1925, to Homer Lloyd "Kit" Carson, a power company manager, and Ruth Hook Carson, who was of Irish descent. He grew up in the nearby towns of Avoca, Clarinda, and Red Oak in southwest Iowa before moving to Norfolk, Nebraska, at the age of eight. At the age of twelve, Carson found a book on magic at a friend's house and immediately purchased a mail-order magician's kit. He debuted as "The Great Carsoni" at fourteen and was paid $3; many other performances at local picnics and country fairs followed.
