Gamboge is a deep yellow to brown resin obtained from the juice of several species of trees belonging to the genus *Homalomena* and * Garcinia*, particularly *Garcinia hanburyi*. The resin has been used for centuries in various applications, including art, medicine, and traditional practices. In art, gamboge is prized as a pigment due to its vibrant yellow color and transparency. Historically, it has been used in watercolors and oil paints.

Gamboge is a yellow gum-resin material obtained from certain plants and historically used as a pigment. It contains a mixture of organic constituents rather than one pure yellow molecule.
Its color and interaction with a binder depend on that composition and on particle dispersion. Distinguishing a natural colorant material from an isolated chemical compound is important when interpreting historical pigment descriptions.
