Phthalocyanine Blue (15ml Watercolours)


Green-Blue, Transparent

Phthalocyanine Blue is a powerful, transparent green-blue which needs to be handled with some care. It has been chosen because it will give very bright greens when mixed with our Hansa Yellow and a wide range of transparent blue greens with Phthalocyanine Green. Such clear blue greens cannot be mixed any other way.
