insoluble organic or inorganic substance which gives colour to paint when ground and suspended in vehicle (or medium) such as water or oil Fresco paint is suspended in water and usually made of earth colours such as ochres and other minerals that can withstand the alkaline action of lime
Any material from which a dye, a paint, or the like, may be prepared; particularly, the refined and purified coloring matter ready for mixing with an appropriate vehicle
dry coloring matter (especially an insoluble powder to be mixed with a liquid to produce paint etc) color or dye with a pigment; "pigment a photograph"
Finely ground, natural or synthetic, inorganic or organic, insoluable particles which, when dispersed in a liquid vehicle to make paint, may provide, in addition to color, many of the essential properties of a paint--opacity, hardness, durability, and corrosion resistance
A solid colorant used in various inks Unlike dye, this material does not dissolve in the inks solvent but remains a particle Because of this, it gives improved coverage over certain substrates and usually has improved fade resistance
A powder-form of color that can be combined with an acrylic base for paint or made into a "pigment dye " It isn't actually a dye, it sits on the surface of the fibers
An insoluble finely ground powder, either natural, synthetic, inorganic or organic that provides color, hardness, durability, hiding and corrosion resistance to paint
A compound that gives colour to body tissues Naturally found in tissues it is of particular importance in providing colour to the fish for camouflage Used in some fish diets to enhance the colour of the flesh to make a product that is more readily accepted by markets Chemicals such as astaxanthin and canthaxanthin (collectively known as carotenoids) are used, for example, to give farmed salmon and trout a pink colouration to their flesh, which would other wise be white The pink colouration mimics the colour found in wild fish, which is obtained by the consumption shrimps, which naturally contain the pigment Chlorophyll, which gives algae it's green colour is also classed as a pigment The addition of pigments to salmonid feeds composes only 0 005 - 0 01 of the feed volume, but can comprise as much as 15% of the price of the feed Pigments are also very important in the development of eggs and larvae of many species
Finely ground natural or svnthelic, inorganic or organic, insoluable particles which, when dispersed in a liquid vehicle to make paint, may provide, in addition to color, many of the essential properties of a paint - opacity, hardness, durability, and corrosion resistance
A pigment is a substance that gives something a particular colour. The Romans used natural pigments on their fabrics and walls. a natural substance that makes skin, hair, plants etc a particular colour (pigmentum, from pingere ). Any intensely coloured compound used to colour other materials. Unlike dyes, pigments do not dissolve; they are applied as fine solid particles mixed with a liquid. In general, the same ones are used in oil-and water-based paints, printing inks, and plastics. They may be inorganic compounds (usually brighter and longer-lasting) or organic compounds. Natural organic pigments have been used for centuries, but today most are synthetic or inorganic. The primary white pigment is titanium dioxide. Carbon black is the most usual black pigment. Iron oxides give browns, ranging from yellowish through orange to dark brown. Chromium compounds yield chrome yellows, oranges, and greens; cadmium compounds brilliant yellows, oranges, and reds. The most common blues, Prussian blue and ultramarine, are also inorganic. Organic pigments, usually synthesized from aromatic hydrocarbons, include the nitrogen-containing azo pigments (red, orange, and yellow; see azo dyes) and the copper phthalocyanines (brilliant, strong blues and greens). Chlorophyll, carotene, rhodopsin, and melanin are pigments produced by plants and animals for specialized purposes
Finely ground insoluble particles dispersed in coatings to influence properties such as color, corrosion resistance, mechanical strength, hardness, durability, etc Particles may be natural or synthetic and also inorganic or organic
The ferromagnetic particles in a magnetic stripe are usually called magnetic pigments since they are made in a fashion similar to pigments used in the paint and coloring industries; see Gamma Ferric Oxide, Barium Ferrite and Strontium Ferrite
Any inorganic, insoluble material of fine particle size added to the wet end of a paper machine or used as a surface treatment Generally used for economy, color, brightness and opacity characteristics
