A useful take on an artist's staple, ultramarine blue with a distinctive green shade. Maybe this is a better option than phthalo blue for a slightly less powerful blue which leans towards green.
It is very well suited to seascapes and landscapes.
'This is an intense deep greenish-shade blue colour from inorganic pigment of sodium aluminum silicate composition. It is a transparent, fine grained colour with high tinting strength. It is ground in linseed oil without additives to change the effect of the pigment and oil mixture. As a result, the paint is long producing slightly stringy brushmarks due to the hydrophilic nature of ultramarine.
Ultramarine pigments are sodium aluminum silicates of the composition Na8Al6Si6O24. Small sulphur containing anions are bound as chromospheres in the interstices of the crystal lattice to equalize the charge. Depending on composition, blue, red, green or violet pigments can be obtained, the hue being altered by varying the amount of silica.'
