Etymology
The term "powder-blue" is a compound adjective originating in the 17th or 18th century. It originally referred to the specific pale blue colour produced by smalt, a deep blue glass pigment made from cobalt, which was ground into a fine powder for use in laundry to whiten white fabrics and counteract yellowing. The first element, "powder," directly references this finely ground substance, while "blue" denotes the resulting hue. Over time, the term's meaning generalized to describe any soft, pale, slightly greyish blue colour, retaining the association with the delicate, dusty quality of powdered pigment.
