Refers to lead white, however as with many paint names, the usage has changed over time. In the 19th century the name referred to a paints that contained a mixture of lead white (basic lead carbonate) and chalk. An earlier usage included pigments made with plates of lead or tin. Currently lead white is the favored interpretation, however some companies draw inspiration from the lead-chalk combination in their usage of the term.
