Cobalt Blue Turquoise is a color that has been missing a long time as a pigment in the color spectrum and thus closes a gap between Phtaloblue and Phtalogreen. One can even quite good remixe the color when combining Phtaloblue, Phtalogreen and white, however, this mixture is then translucent.
As the color wheel opposite color of a warm red tone as cadmium red medium, one can thus mix a very opaque black.
It can also be used very well in combination with cobalt blue for a clear and pure sky.
