Lead chromate is a chemical compound, a chromate of lead. It is used in some pyrotechnic compositions, especially delay compositions, as an oxidizer. Up to the late 1800s it was used to impart a bright yellow color to some types of candy. Lead(II) chromate and lead(II) carbonate were the most common lead-based paint pigments.
