Art Spectrum® Spectrum Orange is a rich, deep, orange with lovely warmth produced as an economic alternative to the traditional cadmium orange.
It is based on the powerful reddish Pyrazolone orange and cooled with a touch of the ever so slightly greenish Arylide yellow.
Both are relatively modern pigments, developed in the 19th century.
