Alternatively, other variants, like ''Celeste polvere,'' ''Pallido'' and ''Velato'', are visible towards the horizon when the Sun is near to the zenith, always with conditions for good visibility. In the afternoon, always with good conditions, these three types of celeste, together with softer and less bright shades of celeste, are visible at a Angle, 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 conditions; other shades of blue are often visible in the sky, as ''Light Sky Blue'' and similar gradations, among which is 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 spectrum and so celeste, which is very close to the white with a

Bleu celeste ("sky blue") is a rarely occurring tincture (heraldry), 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 (heraldry), azure, which is the standard blue used in heraldry.
