Sky blue refers to a collection of shades comparable to that of a clear daytime sky. Typically it is a shade of cyan or light teal, though some iterations are closer to light azure or light blue. The term (as "sky blew") is attested from 1681. A 1585 translation of Nicolas de Nicolay's 1576 Les navigations, peregrinations et voyages faicts en la Turquie includes "the tulbant [turban] of the merchant must be skie coloured".
Celeste (Spanish: [θeˈleste, se-], Italian: [tʃeˈlɛste], English: /sɪˈlɛst/) is the colloquial name for the pale turquoise blue colour. The same word, meaning "of the sky", is used in Spanish, Portuguese and Italian for the colour. Etymologically, it is derived by Latin term caelestis, that means del cielo in Italian. There are two "conventional" colours denominated celeste, according to the colour models. One is the pure Celeste, (HEX#B2FFFF; RGB 178,255,255) which may be referred as the "true" celeste as it is traditionally or officially understood; in English, it may also be referred to as Italian sky blue (blu cielo italiano) and Bianchi Green, referring to Bianchi, the famous Italian company for bikes, the first in the history of vehicles, whose colour is characteristic.
The Japanese equivalent is known as sora iro or mizuiro, referring to the colour of the sky or its reflection on the sea. The other one is also another conventional celeste (HEX #99cbff and RGB 153,203,255) containing 100% of blue, associated to a more generic colour of the sky and remembering a type of light zenithal blue and the next sky blue gradations.
