Ultramarine Blue is an inorganic pigment whose color
has been classified as Pigment Blue 29, C.I. 77007 by
the Color Index System. Chemically it is a sodium
alumino-sulphosilicate. This pigment is the synthetic
form of Lazurite.
Ultramarine Blue has a clean and bright reddish blue
shade. This makes Ultramarine Blue different than any

In addition to this very specific reddish blue shade,

neutralizes yellowish shades. Moreover, when using

change of color in function of the illuminant) does not
occur. This whitening effect is widely appreciated in
many fields of application such as detergents, plastics,
paints etc.
