Horadam colors can be lifted from a dried palette without forming small bubbles. Colors flow evenly and are fully intermixable. Horadam helps the artist maintain full control of color, even on softer papers.
Color Swatch created using heavy application/diluted application and was applied on cold press watercolor paper (150 lb) material.
Schmincke's modern recreation of Prussian Green is lightfast, and is well suited for bluish shadings in landscape painting.
organic, vat dyes
complex, insoluble anthraquinone
Indanthrene Blue is a clear, clean, deep blue organic pigment. It has moderate to high tinting strength and is not as overpowering as Phthalo Blue. Hansa Yellow Deep, Benzimidazolone Orange, and Raw Umber are its best mixing complements.
Indanthrene Blue is permanent with excellent lightfastness in both masstone and tints.
Indanthrene Blue varies in its acute toxicity, though toxicity is generally slight.
Indanthrene Blue is the oldest vat dye, discovered and patented in 1901 by Rene Bohn. It is considered the first anthraquinone vat dye, a group of dyes characterized by excellent lightfastness. The pigment originates from this dye.
polychlorinated copper(II) phthalocyanine

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. It 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.
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.
Phthalo Green has no significant hazards, but it contained PCBs (polychlorinated biphenyls) until 1982.
This bright blue-green was developed in 1935 and has been in use since 1938.
