This cool turquoise blue is ideal for creating form or indicating space. It is a medium-staining semi opaque pigment with wonderful granulating properties. A good substitute for Cerulean Blue, Manganese Blue Hue offers an additional advantage: it mixes well with other non-staining semi opaques to create a mottled texture in underlying colours. Note: true Manganese Blue, discontinued from product lines due to environmental concerns and toxic by-product, has been replaced in the DANIEL SMITH line with a formulation which closely resembles it. The result is a safe, high quality lightfast pigment with the colour we adore-Manganese Blue Hue. Light fastness: Very Good Medium Staining Granulation: Yes Transparent
