Schiffermüller's system called for a series of charts, as Schüffer's system had. He used blue rather than Schüffer's choice, red, as his example. The resemblance is only superficial, however, as they offer different information. Source: From Ignaz Schiffermüller, Versuch eines Farbensystems (Vienna, 1772), plate II.
