13. Ciel Color 161 - #92A1CF

Bleu celeste ("sky blue") is a rarely occurring tincture in heraldry (not being one of the seven main colours or metals or the three "standard 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.

Initially considered to be European rather than English or Scottish, after the First World War it became more prevalent in England in badges of coats relating to the Royal Air Force, or the arms of those with some RAF connection. While in the post-WWI period bleu-celeste is depicted as a darker shade, in prior times it was depicted as very light, and has even been treated as a metal, as azure charges have been placed on a bleu celeste field, and vice versa.
