Napthol Red, the napthol pigments were first patented in 1911 and used initially as cotton dyes, then in the 1920's they were 'laked' (precipitating a dye with a metallic salt to stabilize it) and began to appear as artist's colours.
In masstone, a luminous red that leans towards orange, described as slightly opaque by Michael, which means used thinly it is rather transparent and more thickly it becomes opaque in appearance.
A powerful tinter that produces much more satisfying pink orange tints than you get with a Cadmium, they are brighter and warmer.
It's almost a transparent alternative to Cadmium Red Light with better tints with white added.
High pigment load, a little goes a long way.
