Powder blue is a pale shade of blue.[1] As with most colours, there is no absolute definition of its exact hue, but according to Etymology Online, powder blue originally referred in the 1650s to powdered smalt (cobalt glass) used in laundering and dyeing applications, and it then came to be used as a colour name from 1894.[2]
Although smalt itself is a deep, dark blue hue, powder blue is nowadays depicted as more of a pale cobalt blue as illustrated by the examples below, which show powder blue as defined by British and Australian Standards for paint colours along with an example of one manufacturer's actual Powder Blue paint, and a consensus definition produced by an online colour names survey in which 140,000 people took part. It can be seen that although the sources differ on how pale or saturated a colour "powder blue" is, they broadly agree as to its hue.

There is also a recorded use of powder blue as a colour name in English in 1774, however the sources offer more than one possible colour of this name, including a blue-grey and a dark unsaturated blue.[7]
