About this product range

Schmincke Horadam Gouache is more than just opaque watercolor. Since no white is added to Horadam Gouche to artifically boost its covering power, it can create crisp color blends like no other gouache. Of the 48 colors, all but 8 are based on a single pigment.

Like Horadam Watercolors, colors thin with water and are easily rewetted if left to dry on the palette. Horadam Gouache is so finely ground, it can even be used for 0.15 mm airbrush work.

Many other brands of gouache are "designer" gouaches, with an emphasis on accurate pre-mixed colors for use by the designer. By contrast, Horadam is a "fine artist" gouache, with an emphsis on providing the classic range of pigments as pure, single-pigment colors.

Phthalo Green

Pigment code
PG36
Type
organic
Chemical name
polybromopolychlorinated copper(II) phthalocyanine
Chemical formula
C32H3Cl13CuN8 to C32HCl15CuN8 or C32H16CuN8Cl15 (PG7) or C32Br6Cl10CuN8 (PG36)
Properties
Phthalo Green is a transparent, cool, bright, high intensity color used in oil and acrylics. It comes from a Phthalocyanine Blue pigment where most of the hydrogen atoms have been replaced with chlorine, forming highly stable molecules. Pigment PG36 differs from PG7 in that a portion of the chlorine atoms are replaced with bromine atoms, which are reactively similar, but cause a yellow shift that is especially noticeable in mixtures. Phthalo Green has similar pigment properties and permanence to Phthalo Blue. It is slow drying and an excellent base color for mixing a range of bright greens. Phthalo Green is considered a very good alternative to Viridian because it is intense and mixes well and can be used to emphasize mineral colors in various tints. However, its tinting strength is very high, so it can overpower other colors. This pigment most closely resembles the discontinued and toxic Verdigris.
Permanence
Phthalo Greens are completely lightfast and resistant to alkali, acids, solvents, heat, and ultraviolet radiation. They are currently used in inks, coatings, and many plastics due to their stability and are considered a standard pigment in printing ink and the packaging industry.
Toxicity
Phthalo Green has no significant hazards, but it contained PCBs (polychlorinated biphenyls) until 1982.
History
This bright blue-green was developed in 1935 and has been in use since 1938.
