Each Rembrandt watercolor uses the purest quality of pigments and gum Arabic. It is formulated to achieve the maximum transparency and reflection of light while maintaining the highest concentration of pigment. All colors are highly permanent.

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.

nickel azomethine yellow
Nickel Azo Yellow is a transparent, moderately staining yellow pigment with high tinting strength. It is considered a good color match in botanical and landscape painting for natural gamboge (NY24), a historic yellow pigment with fair to poor lightfastness.
Nickel azomethine yellow has excellent lightfastness.
Nickel azo yellow pigment is mildly toxic, and is often labeled as hazardous. Avoid respiratory and skin exposure to pigment dust. It should be disposed of properly with other hazardous wastes, not washed down the sink. However, the contribution of artist pigments to levels of nickel metal complexes in the environment is almost insignificant. Nickel is often present in the environment naturally. Nickel is used heavily in steelmaking, and in many industrial processes and products.
Nickel azomethine yellow has been developed as an artist pigment becasue it is a close match for gamboge, a historic yellow.
