Sky blue

Sky blue is a colour that resembles that of an unclouded sky around noon (azure) reflecting off a metallic surface. The entry for "sky-blue" in Murray's New English Dictionary (1919) reports a first sighting of the term in the article on "silver" in Ephraim Chambers's Cyclopaedia of 1728. However, many writers had used the term "sky blue" to name a colour before Chambers. For example, we find "sky blue" in A Collection of Voyages and Travels (London: Awnsham and John Churchill, 1704), vol. 2, p. 322, where John Nieuhoff describes certain flowers: "they are of a lovely sky blue colour, and yellow in the middle". The sense of this colour may have been first used in 1585 in a book by Nicolas de Nicolay where he stated "the tulbant [turban] of the merchant must be skie coloured".[1]

Celeste (Spanish: [θeˈleste, se-], Italian: [tʃeˈlɛste], English: /sɪˈlɛst/) is the colloquial name for the pale turquoise blue colour. In Spanish and Italian, as the name indicates (celestial), it is an attempt to reproduce the colour of clear skies. In English, this colour may also be referred to as Italian sky blue. The Japanese equivalent is known as sora iro or mizuiro, referring to the colour of the sky or its reflection on the sea.[2]

Bleu celeste ("sky blue") is a rarely occurring tincture in heraldry (not being one of the seven main colours or metals or the three "staynard colours"). This tincture is sometimes also called ciel or simply celeste. It is depicted in a lighter shade than the range of shades of the more traditional tincture azure, which is the standard blue used in heraldry.[3]

In culture
Sports
  • Argentina: Following the colours of the Flag of Argentina, in which sky blue (celeste in Spanish) is the predominant colour, many Argentine sport teams feature the colour, including Racing Club de Avellaneda, Belgrano de Córdoba, Racing de Córdoba, Club Atlético Temperley, Atlético Rafaela, Villa San Carlos, Gimnasia y Esgrima de Jujuy, Gimnasia y Tiro de Salta, and Gimnasia y Esgrima de Concepción del Uruguay. In addition, the Argentina national football team is known as the albicelestes due to the white-and-sky blue striping on their jerseys. This colour scheme is featured in other prominent national squads in popular sports such as rugby, field hockey, polo or volleyball, to name a few.
  • Australia: Sky blue is the main colour of the Australian rugby league team, New South Wales Blues, as it is the official colour of the state they represent.
  • Italy: Celeste is the main colour of the football team S.S.Lazio of Rome, and one of the two main colours (the other being dark blue) of the football team Calcio Lecco 1912 of Lecco.
  • United Kingdom Manchester City adopted sky blue as the main colour of their home jersey in 1894 and have used that ever since then.[10]
  • Uruguay: The Uruguay national football team has worn a sky blue jersey since 1910, after Uruguayan club team River Plate F.C. wore sky blue while defeating contemporary Argentine powerhouse Alumni Athletic Club. The national team is nicknamed La Celeste. As in Argentina, a number of Uruguayan club teams use sky blue in their uniforms, such as C.A. Cerro, Club Atlético Torque, Club Oriental de Football, and Rocha F.C.
