Like so many of their paints, as far as I know this is unique to Wallace Seymour.
Based on the pigment PBr 24 which is sometimes used as a deep Naples Yellow replacement this paint creates beautiful muted orange hues, somewhere between a tangerine and a burnt orange colour in masstone. It has strong tinting power and it makes slightly 'greyed' sandy Oranges when mixed with White.
Very lightfast and excellent hiding power, this paint has a lot of potential in all kinds painting practice, muted oranges are not always very easy to mix particularly with the powerful Cadmium Orange, to reduce it's chroma can present difficulties, with this lower chroma/cooler orange the work is done.
