Metallics : Copper, Yellow Gold, Red Gold
Metallic pigments produced from metal alloy powders that
have undergone surface treatment. Suitable for all oil and
water-based binders except acrylic and fresco. Apply a varnish
over metallic colors to prevent oxidation.
Fluorescent Pigments
Fluorescence, which results from the pigments’ ability to
transform light, provides unique tonalities that only exist
outside nature. These pigments are extremely unstable, and are
recommended only for temporary artworks. Very poor
lightfastness. Not recommended for fresco.
Phosphorescent Pigments : Yellow-green
Inorganic, phosphorescent Zinc sulfide powders. Recommended
for use with water-based binders (except fresco). Since excessive
grinding weakens their phosphorescent qualities, pigments
should be mixed gently with a binder, or ground lightly.
Humidity and ultraviolet rays can darken these pigments. If the
colours are exposed to direct light, keep the humidity of the
environment under 50%. Applied in favourable conditions, the
special properties of these pigments can last for years.
Lakes
Synthetic alizarin was formulated from tar in 1868 by
Groebe and Libermann. It perfectly reproduces Madder
(Garance), traditionally extracted from the ground root
“Rubian tinctorium”.
Alizarin Scarlet Lake
Nitrogenous “azo” lake. Bright, extremely luminous,
transparent red. Principally used in oil, watercolour, tempera
and acrylic. Average lightfastness. In oil, used primarily in
glazes, because when applied in thick pastes,it is prone to
cracking. Not recommended for fresco.
Alizarin Red Lake
Alizarin lake on aluminum hydrate base. Deep, transparent
red with a carmine hue. Average lightfastness. High tinting
strength. When used in oil, has a tendency to crack. Slow
drying. Suitable for all techniques, except fresco.
Black Lake
Synthetic aniline black that is velvety and intense. In tints,
takes on a slightly bluish hue. Average lightfastness. Not
recommended for fresco.
Solferino Lake (Tyrian Rose)
Calcified aluminum hydrate base lake. Very bright pink. Poor
lightfastness, excellent tinting strength. Because of its fugitive
nature, use with discretion. Not suitable for fresco.
Iridescent Pigments
Titanium dioxide. Iridescent pigments undergo surface
treatment with mica ; their level of iridescence varies
according to the mica content. As a result of reflections and
light interference, they may take on very different colours.
Extremely lightfast, excellent covering power, non-toxic. Used
for a wide range of applications, including cosmetics.
Suitable in all binders, including oils, vinyl paints, resins,
etc…
Avoid grinding iridescent pigments ; grinding may destroy
their “mother-of-pearl” effect.
