Egyptian blue: a synthetic pigment of calcium copper silicate (CaCuSi 4 O 10). Thought to be the first synthetically produced pigment. Han blue: BaCuSi 4 O 10. Azurite: cupric carbonate hydroxide (Cu 3 (CO 3) 2 (OH) 2). Basic copper carbonate: Cu 2 (OH) 2 CO 3. Iron pigments. Prussian blue (PB27): a synthetic inert pigment made of iron and ...
A pigment is a powder used to add color or change visual appearance. Pigments are completely or nearly insoluble and chemically unreactive in water or another medium; in contrast, dyes are colored substances which are soluble or go into solution at some stage in their use.
Flowers. An example is the bluish purple flowers of the Japanese garden iris (Iris ensata). [2]The characteristic floral jade coloration of Strongylodon macrobotrys has been shown to be an example of copigmentation, a result of the presence of malvin (the anthocyanin) and saponarin (a flavone glucoside) in the ratio 1:9.
Lutein is a yellow pigment found in fruits and vegetables and is the most abundant carotenoid in plants. Lycopene is the red pigment responsible for the color of tomatoes. Other less common carotenoids in plants include lutein epoxide (in many woody species), lactucaxanthin (found in lettuce), and alpha carotene (found in carrots). [8]
Cobalt blue pigment Blue pigments are natural or synthetic materials, usually made from minerals and insoluble with water, used to make the blue colors in painting and other arts. The raw material of the earliest blue pigment was lapis lazuli from mines in Afghanistan, that was refined into the pigment ultramarine .
Pelargonidin can be found in red geraniums (Geraniaceae). It is the predominant pigment causing the red coloration in the spathes of Philodendron (Araceae). The orange-coloured flowers of blue pimpernel (Anagallis monelli, Myrsinaceae) have a higher concentration of pelargonidin pigment.
