Red lead 丹(tan): The common name for a heavy, opaque, orange-red pigment composed of Lead tetroxide. Although chemically equivalent to the mineral minium, red lead has been synthetically prepared by roasting lead white (480 C) since before the 5th century BCE.

Yellow ochre has been found.... (write something)

-Gamboge does not fluoresce under UVA radiation and does not produce a distinct pattern using Excitation Emission Matrix (EEM) spectroscopy. Of the possible yellow colorants analyzed, it is the only bright yellow colorant that does not fluoresce but also absorbs the UVA induced fluorescence emitted by the paper. This negative indication was sometimes used to assign the presence of gamboge.
