Celeste (pronounced che-les-te in Italian, se-les-te in Spanish and Se-lest in English) is the colloquial name for the turquoise blue colour associated with the Italian Bianchi Bicycle Company and sometimes known as Bianchi Green. In Italian, as the name indicates (Celestial), it is an attempt to reproduce the colour of clear skies. In English, this colour is most often referred to as sky blue.

The Italian Wikipedia cites Il dizionario dei colori: nomi e valori in quadricromia by S.Fantetti and C.Petracchi and describes multiple variants of Celeste as shown below, plus details as defined in the infobox above.

Devin Garret Townsend (born May 5, 1972) is a Canadian musician and record producer. He was the founder, songwriter, vocalist, and guitarist in extreme metal band Strapping Young Lad from 1994 to 2007 and has had an extensive career as a solo artist.

After performing in a number of metal bands in high school, Townsend was discovered by a record label in 1993 and was asked to perform lead vocals on Steve Vai's album Sex & Religion. After recording and touring with Vai, Townsend was discouraged by what he found in the music industry, and vented his anger on a solo album released under the pseudonym Strapping Young Lad. He soon assembled a band under the name, and released the critically acclaimed City in 1997. Since then, he has released three more studio albums with Strapping Young Lad, along with solo material released under his own independent record label, HevyDevy Records. Townsend's solo albums, a diverse mix of hard rock and progressive metal, have featured a varying lineup of supporting musicians. In 2002 he formed The Devin Townsend Band, a dedicated lineup which recorded and toured for two of his solo releases.

Peter Brian Gabriel (born 13 February 1950) is an English singer, musician, and songwriter who rose to fame as the lead vocalist and flautist of the progressive rock group Genesis.

More recently, Gabriel has focused on producing and promoting world music and pioneering digital distribution methods for music. He has also been involved in various humanitarian efforts. Gabriel has won numerous music awards throughout his career, including three Brit Awards—winning Best British Male in 1987, six Grammy Awards, thirteen MTV Video Music Awards, and in 2007 he was honoured as a BMI Icon at the 57th annual BMI London Awards for his “influence on generations of music makers.” Gabriel was also awarded the Polar Music Prize in 2009, and was inducted into the Rock and Roll Hall of Fame as a member of Genesis in 2010.
