Primary color

Primary colors are sets of colors that can be combined to make a useful range of colors. For human applications, three primary colors are typically used, since human color vision is usually trichromatic.

For additive combination of colors, as in overlapping projected lights or in electronic visual displays, the primary colors normally used are red, green, and blue. For a subtractive combination of colors, as in mixing of pigments or dyes for printing, the colors magenta, yellow, and cyan are normally used. However, red, yellow, and blue are commonly used as primaries when painting or drawing. See RGB color model, CMYK color model, and RYB color model for more on these popular sets of primary colors.

In an additive system, choices of sets of primary colors are nearly arbitrary, subject to weak constraints from the spectral sensitivities of each of the human cone photoreceptors. An early color photographic process, autochrome, typically used orange, green, and violet primaries. However, unless negative amounts of a color are allowed, the gamut will be restricted to the color triangle defined by the choice of primaries.

Sesame Street

Sesame Street is a long-running American children's television series created by Joan Ganz Cooney and Lloyd Morrisett. The program is known for its educational content, and images communicated through the use of Jim Henson's Muppets, animation, short films, humor, and cultural references. The series premiered on November 10, 1969, to positive reviews, some controversy, and high viewership; it has aired on the U.S.'s national public television provider (PBS) since its debut, with its first run moving to premium channel HBO on January 16, 2016.

The show has undergone significant changes throughout its history. The format of Sesame Street consists of a combination of commercial television production elements and techniques which have evolved to reflect the changes in American culture and the audience's viewing habits. With the creation of Sesame Street, producers and writers of a children's television show used, for the first time, educational goals and a curriculum to shape its content. It was also the first time a show's educational effects were studied.

OK Go

OK Go is an American alternative rock band originally from Chicago, Illinois, now based in Los Angeles, California. The band is composed of Damian Kulash (lead vocals, guitar), Tim Nordwind (bass guitar and vocals), Dan Konopka (drums and percussion) and Andy Ross (guitar, keyboards and vocals), who joined them in 2005, replacing Andy Duncan. They are known for their often quirky and elaborate one-take music videos.

The original members formed as OK Go in 1998 and released two studio albums before Duncan's departure. The band's video for "Here It Goes Again" won a Grammy Award for Best Music Video in 2007.

History

Formation and early years (1998–2000)

The band's lead singer, Damian Kulash, met bassist Tim Nordwind at Interlochen Arts Camp when they were 11. Kulash was in for graphic design, Nordwind for music. The band name comes from their art teacher saying, "OK... Go!" while they were drawing. They kept in touch after camp, often exchanging mixtapes which influenced each other's musical taste and their future sound. They met the band's former guitarist and keyboardist Andy Duncan in high school. Nordwind and Duncan moved to Chicago for college, where they formed the band Stanley's Joyful Noise with drummer Dan Konopka. The name OK Go was adopted in 1998, when Kulash moved to Chicago to join the band.
