Ancient oriental watercolors are characterized by their delicate hues. Now today's artist can journey back into time to create with the same timeless palette used by Japanese and Chinese artists 15 centuries ago.
Color Swatches created using heavy application/diluted application and were applied on cold press watercolor paper (150 lb) material.
mix of organic pigments
Hooker’s Green is a bright olive-green often sold in a yellowish shade and a bluish shade. Its transparency can range from dull and dark to bright and light because lightness and chroma vary based on manufacturer. Modern varieties have a rich, dark tone that provides a great range when mixing. Hooker’s Green is particularly good for landscape painting when a larger range of foliage is required. Dioxazine Violet is the best mixing compliment in watercolor form.
The permanence and lightfastness of Hooker’s Green varies by brand. As a composite pigment historically mixed from Prussian Blue and Gamboge, its permanence is only fair. Modern replacements for Hooker's Green tend to be mixed with components that have more permanence, such as Phthalocyanine Green, Burnt Umber, and sometimes Hansa or Cobalt Yellow.
Hooker’s Green can be hazardous, but the toxicity level depends on the specific pigments used by each individual manufacturer or brand.
This pigment was originally an unreliable mix of Prussian or Iron Blue and Gamboge. Later, it became a more reliable mix of Cadmium Yellow and Phthalo Blue or Green. It was a staple green for 19th century landscape and botanical painters. Most modern Hooker’s Green paints are yellow greens with a hue angle around 140, or a mix of Phthalo Green and Burnt Umber.
Benzidine Yellow GG
Pigment Yellow 17 is a somewhat greenish yellow that has very high tinting strength and good resistance to solvents.
Pigment Yellow 17 has good lightfastness if prepared using the proper procedures. Because procedures for preparing PY17 vary, artists may want to conduct their own lightfastness tests to verify that the manufacturer has selected quality pigment.
Benzidine dyes are not bioavailable. Although benzidine-based dyes can be reduced to their amine precursors in vivo, creating a compound that is carcinogenic, benzidine dyes are believed to be so insoluble in water that they are unlikely to be absorbed in a quantity sufficient to be carcinogenic.
This Benzidine Yellow dye was first reported by Esitelty in 1949. Initiailly, it was reported to be less lightfast than yellow monoazo pigments, which limited its usefulness. A method for making Pigment Yellow 17 more permanent was patented in 1972 (United States Patent 3785843), and the improved dye became known as Permanent Yellow. Permanent Yellow 17 is widely used in printing inks, textile dyes, paints, plastics, and coatings.
