This color had to be the first paint we produced in the tube! It is not one of the common colors found in art stores, probably because no one knows about it yet. The deep rich pigment has very strong tinting strength. It is a high performance pigment, and will have very good light-fastness, and is not considered toxic. The environmental impact of making this particular family of pigments is less than many other paints because all the chemical reactions are carried out in water. Rubine Red is one to have on the palette. Pr57:1!
