Quinacridone orange (PO48)
Quinacridone orange is a transparent, staining and very intense orange earth-colored pigment that first saw the light of day in 1958. A property, which it unfortunately shares with several other watercolor paints, is that it loses quite a lot of hue when it dries, although value is not affected as much .
There have been rumors that the pigment would cease, that it is not popular among the major pigment users. The manufacturers of artist paints are dependent on the pigment industry for their pigments, their major customers are the plastics industry and manufacturers of car paints and the like, the manufacturers of artist paints are a trifle, so if a paint is not popular with the big users, production is discontinued. This has happened with Quinacridone gold and Nickel dioxin yellow, two of my previous favorites. But quinacridone orange seems to be available for some time to come, an interest from the car industry seems to be the explanation why there are three different manufacturers of the pigment nowadays.
Quinacridone orange can be used as an orange-brown earth color, it is similar in several ways to burnt sienna from Winsor & Newton and Daler-Rowney, both of which use the pigment synthetic iron oxide. The color is not directly brown but more colorful, slightly unclear orange. It is a very beautiful color that I highly recommend.
The color mixes well with many different other colors, it is an asset in all palettes. Especially for those who like to mix themselves. Fantastic blurry greens and violet can be easily achieved but a shortcoming may be that there is no color that is an absolute complementary color, it is difficult to mix a gray color without using a third color in the mix.
The pigment is quite common in different color mixtures but unusual on its own. Only a few manufacturers have Quinacridone orange.
