History

Hansa Yellows were first made in Germany just before WW1 from a series of synthetic dyestuffs called Pigment Yellow. They were intended to be a synthetic replacement for Cadmium Yellow. Permanent Yellow (PY97) represents a further development of this line, with the aim of producing a yellow pigment that is suitable for exterior use.
