Antique artefacts have been studied by chemists, revealing a hitherto unknown use of yellow in Ancient Egypt.

Quote

Kaare Lund Rasmussen's Italian
colleagues from Professor Maria Perla Colombini's research group
at the University of Pisa managed to find traces of two binders,
namely rubber and animal glue. The rubber is probably tapped from
an acacia tree and served as a solvent for powdered pigment. Rubber
was widely used as a binder, and it has also been found on stone
columns in the Karnak Temple and murals in Queen Nefertite's tomb.
(...) The researchers also found these color pigments:
Calcite (white). Gypsum (white). Egyptian Blue (a synthetic pigment,
invented in the 3rd millennium BC). Atacamite (green). Hematite (red).
Orpiment (golden yellow).
