A descriptive colour name from the silvery leaves of the herb. The colour is one of several subtle greyed green tints, found in Chinese celadon ware. It is also to be found in many tapestries notable Flemish works of the sixteenth century.
A colour name popular in the textile and allied trades since 1550. Standardised in 1934. Really an improper name for a specific colour sensation, since Saxon Blue, from which Saxe is derived, is the name of a chemical substance only, a dye from which are produced all tones of blue from light to dark. The word Saxe is not English but is adopted from the French, where it means Saxony or Saxon. Saxony Blue was a universally-used synonym for Smalt as early as 1550. Likewise Bleu de Saxe has long been a synonym for Prussian Blue, but since 1753 Saxon Blue has been most familiar as a widely-used name for indigo extract.
A colour name originally used for Smalt but later used in the textile and allied trades for the colour, standardised in 1934. This colour name has been used from the sixteenth century in connection with Smalt (Cobalt) and Prussian Blue. The more modern colour under this name, which was first used in the latter part of the nineteenth century, was probably derived from one of these earlier colours, but has deviated so much from Smalt that it is the general representation of samples submitted by textile and other colour using industries that is depicted here as Royal Blue.
