Sky blue refers to a collection of shades comparable to that of a clear daytime sky.OED, sky blue, 181142, Typically it is a shade of cyan or light teal, though some iterations are closer to light blue. The term (as “sky blew“) is attested from 1681. A 1585 translation of Nicolas de Nicolay’s 1576 includes “the tulbant [turban] of the merchant must be skie coloured”.Cited as 1585 in Maerz and Paul A Dictionary of Color New York:1930 McGraw-Hill Page 204; Color Sample of Sky Blue: Page 89 Plate 33 Color Sample E6.(File:Clouds Blue Sky 001.jpg|alt=Bright blue sky with clouds|thumb|Bright blue sky with clouds)Displayed at right is the web colour sky blue.

Generically, what is said here for Celeste is valid for the regions between the equator and the two polar circles, including the temperate zones and subtropics. In these zones, the sun remains high enough throughout the year, especially in the warm seasons (spring, summer). Naturally, the closer you are to the equator the higher it will appear. In particular, in the warm seasons, with the inclination of a hemisphere with respect to the sun,WEB, 2023-05-05, NASA Spacecraft Reveal How Earth’s Tilt Causes Seasons in Space Weather – The Sun Spot,blogs.nasa.gov/sunspot/2023/05/05/nasa-spacecraft-reveal-how-earths-tilt-causes-seasons-in-space-weather/, 2024-03-21, blogs.nasa.gov, en-US, WEB, Seasons of the Year,pwg.gsfc.nasa.gov/stargaze/Sseason.htm, 2024-03-21, pwg.gsfc.nasa.gov, WEB, Helmenstine, Anne, 2023-11-04, Why Do We Have Seasons on Earth?,sciencenotes.org/why-do-we-have-seasons-on-earth/, 2024-03-21, Science Notes and Projects, en-US, WEB, 2023-09-22, Why does Earth have 4 seasons every year?,earthsky.org/earth/can-you-explain-why-earth-has-4-seasons/, 2024-03-21, earthsky.org, en-US, there are simultaneously the optimization of sunlight, daylight hours, and so the pure celeste might be visible in the entire region between the horizon and sun both in the morning and afternoon; generally, the higher the sun is during the day and the year, the less visible celeste and variations will be. In particular, in the morning across the sun and the horizon in the early hours with the rising of the star, sometimes even until noon, until they are reduced to a few stripes on the horizon, where the cyan is more intense. In the afternoon, it is the opposite and the pure celeste and similar gradations could be widely visible between the sun and horizon when the star is high, but starting to go down, that is especially in the early afternoon hours. Instead, in the cold season, with a low sun and sunlight, the pure celeste may be visible only at the horizon, where the cyan is more intense for the maximum light, but is more difficult because of the major weather instability. In anyway, since sunlight is strongest at the horizon, that is where the pure celeste is more evident, producing the tonalities of the cyan, very close to the white.

Note that the pure celeste is more evident close to the horizon, where the cyancyanAlternatively, other variants, like Celeste polvere, Pallido and Velato, are visible towards the horizon when the sun is near to the zenith, always with discrete or good conditions of visibility. In the afternoon, always with good conditions, these three type of celeste, togheter to softer and less bright shades of celeste, are visible at straight angle from north to south, until around sunset. In reality, it can be difficult to observe the pure celeste, being the color of a clear day with optimal meteorological factories; other shades of blue are often visible in the sky, as Light Sky Blue and similar gradations, among which the other conventional celeste, similar to the light blue sky colours rather than the pure celeste. One scientific explanation needs to be made: the sun emits light across the entire electromagnetic spectrumWEB, Staff, Astronomy, 2020-07-09, In what part of the electromagnetic spectrum does the Sun emit energy?,www.astronomy.com/observing/in-what-part-of-the-electromagnetic-spectrum-does-the-sun-emit-energy/, 2023-12-22, Astronomy Magazine, en-US, WEB, Robert Lea, 2022-10-24, What color is the sun?,www.space.com/what-color-is-the-sun, 2023-12-22, Space.com, en, and so celeste, which is very close to the white with a RGB of 178,255,255, is very luminous, and so visible in the direction of the sun because it is there the maximum quantity of solar light, especially towards the horizon, even if human eyes can only perceive the visible light. Here because celeste and variations are easier to be visible in the warm seasons because of the inclination of a hemisphere with respect to the sun, spring and especially summer, with the optimization of solar light, hours of daylight and meteorological factors.

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.Scott-Giles, C. W. (1958).
