Sky blue

Sky blue is a colour that resembles the colour of the unclouded sky at 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 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 associated with Italian bicycle manufacturer Bianchi S.p.A 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 may also be referred to as Italian sky blue. The Japanese equivalent is known as sora iro or mizudori, referring to the color 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]

Bianchi bicycles

Bianchi bicycles are traditionally painted celeste, also known as Bianchi Green (and sometimes, incorrectly Tiffany Blue). Contradictory myths say celeste is the colour of the Milan sky; the eye colour of a former queen for whom Edoardo Bianchi made a bicycle; and that it was a mixture of surplus military paint.

The exact shade of turquoise used by the company has varied over time, but has always been described as celeste.[5] In Anglophone countries, celeste is sometimes reported as Pantone -#332 (Seafoam green [6]) (or #333), and with various other shades.

Deep sky blue is an azure-cyan colour associated with deep shade of sky blue.

Deep sky blue is a web colour.

This colour is the colour on the colour wheel (RGB/HSV colour wheel) halfway between azure and cyan.

The traditional name for this colour is Capri.[9]

The first use of Capri as a colour name in English was in 1920.[10]

The colour Capri in general is named for the azure-cyan colour of the Mediterranean Sea around the island of Capri off Italy, the site of several villas belonging to the Roman Emperor Tiberius, including his Imperial residence in his later years, the Villa Jovis. Specifically, the colour Capri is named after the colour of the Blue Grotto on the island of Capri.[11] as it appears on a bright sunny day. Today the island of Capri is a resort island popular with tourists.

The colour name deep sky blue for this colour did not come into use until the promulgation of the X11 colour list in 1987.

The name Capri is still used for this colour as well as the name deep sky blue.
