Phthalo Turquoise is in the color range between phthalo blue and phthalo green and has a unique, blue-green hue. Since the pigment is difficult to work with, it is only recommended for watercolour and oil. The pigment has very poor wettability and must be rubbed carefully to work it into the binder. When this is done, it tends to stick together on the plate or in the rubbing tray to form a dark, black-green mass. One can only counteract this to a limited extent by adding fillers such as champagne chalk or the finest glass powder. In acrylic or tempera, the colour tone is dark green. In watercolour, this pigment develops its full luminosity and a hue ranging from dark green to turquoise. It is best to rub it directly with Kremer watercolour painting medium. In oil, Phthalo Turquoise must be carefully rubbed on, it dries only slowly, the colour tone varies here from almost black in opaque to bright turquoise in glazed colour application.
