What do Red and Blue make? Purple, I would say this hue is a blueish purple or a cool purple or a reddish violet. How is that for confusing! Such is the nature of applying words to subjective opinions about colour.
Simply this is a purple hue, very rich and dark in masstone and providing tints of cool lilacs and violets. It has the semi-transparent (verging on totally transparent) nature of Ultramarine pigments which I personally find very useful.
Ultramarine pigments can be produced to encompass all spectrums of blue from cool to warm. The pigment is sourced from France and has a high level of purity tangible in the paint.
