Primary Blue is a surprise package for the artist. Primary Yellow and Primary Red are designed to work with it in 3, 4, and 5 color mixing methods and Primary Blue works perfectly for that as expected, but while Primary Yellow and Primary Red work in conventional color mixing scenarios in a way very similar to the pigments near to them on the color chart and so cannot be considered as unique independent colors, Primary Blue is a unique color that is valued by artists using a wide variety of techniques.
