Chrome yellow (C.I. Pigment Yellow 34), see lead(II) chromate.
Due to its high toxicity, Chrome Yellow C.I. Pigment Yellow 34 has been banned in the EU since 2015, but may continue to be used in other parts of the world. Bismuth vanadate C.I. Pigment Yellow 184 is often used as a substitute. The former RAL 1007 »Chrome Yellow« is now called RAL 1007 »Daffodil Yellow« to avoid confusion with the toxic lead(II) chromate.
RAL 1007 »Daffodil Yellow« is used to mark screw locks on Bundeswehr vehicles, for warning signs, and MLC signs (Military Load Class) on vehicles, bridges and routes.
