Southern Ocean Blue is the sort of deep turquoise color that is found in the deep oceans. It is a blend of green and blue phthalocyanine and this makes a transparent and very dark turquoise color. A deep transparent and very permanent blueish turquoise color like this was not possible for the artist to use before the early 20th century. Phthalocyanine has been of extraordinary benefit to the artist.
