Sennelier Oil Pastels are a benchmark in the art world: lipstick soft, highly pigmented pastels made in France with the same top-quality components found in all Sennelier colors.

Developed in collaboration with Pablo Picasso, they combine pure pigments, an exceptionally pure synthetic binding medium, and pH-neutral mineral waxes to create an oil pastel unlike any other.

Each stick is packed with an extraordinarily high pigment load, giving it superior covering power, exceptional brightness, and a high degree of lightfastness (with the exception of metallic and fluorescent colors).

The balance of wax and binder results in a uniquely rich, smooth texture that allows artists to work with freedom, whether creating thin veils of color or bold, impasto-like strokes.

The binder is inert and non-siccative, meaning it won’t oxidize, crack, or alter over time. Combined with mineral wax, this ensures excellent surface stability and makes blending and layering effortless.

Hooker’s Green

Pigment code
PG8
Type
mix of organic pigments
Chemical formula
C30H18FeN3O6Na
Properties
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.
Permanence
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.
Toxicity
Hooker’s Green can be hazardous, but the toxicity level depends on the specific pigments used by each individual manufacturer or brand.
History
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.
