Cerulean blue
Cerulean blue is a cerulean (light blue or azure) pigment used in artistic painting. It is particularly valuable for painting atmospheric shades because of the purity of the blue (specifically the lack of greenish hues). The pigment is regarded as permanent: in oil, no other blue pigment retains color as well.
