Sky blue


Sky blue is a colour that resembles the colour of the unclouded sky at noon reflecting off a metallic surface. The entry for "sky-blue" in Murray's New English Dictionary 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, 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".

Variations

Celeste

Celeste 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, 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.
Bleu celeste is a rarely occurring tincture in heraldry. 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.
