This is such a rich, deep colour and very useful.
It subtle transparency lends itself to glazing, however it so rich in pigment it is fascinating to explore it in mixes where it is not lost like some semi-transparent pigments. Because of its clarity and relative transparency the addition of yellows or blues brings about bright fire engine reds or deep meditative violets.
This is a very similar pigment used by the printing industry as their primary red in the CMYK printing method, why is that important? Well it means it is an incredibly tough, lightfast pigment and can work almost as a primary on the palette although Quinacridone Red would probably be better for this purpose.
Like nearly all the Langridge paints, this is bursting with so much colour there really is nothing in comparison.
