What do pigment numbers mean?
Pigment numbers tell you exactly which pigment was used in the ingredients. For example PB28 is traditionally used for Cobalt Blue. The “PB” means “pigment, blue”, and “28” means that it’s the 28th blue pigment listing in the color index. You also want to look at the quantity of pigments used in the formula.
What function does pigment do in painting medium?

What is called pigment?

Why pigments are used in paints?
Pigments used in paints Pigments give colour and opacity to paints. Amongst the organic pigments, particularly important are azo-, phthalocyanine and anthraquinone derivatives. Other pigments include iron oxides (black, yellow and red), zinc oxide and carbon black.
Which is the example of pigment?
An organic compound that gives a characteristic color to plant or animal tissues and is involved in vital processes. Chlorophyll, which gives a green color to plants, and hemoglobin, which gives blood its red color, are examples of pigments.
What is the difference between paint and pigment?
Pigments produce paints that are more opaque than dyes and have low tinting strength. Opacity is the ability for paint to cover and hide another dried color that it has been applied over. Tinting strength is how well a color mixes with other colors.
What makes a good pigment?
resistance to wetting (because the particles float and, therefore, need a dispersion agent) fatness (giving them a natural gloss) transparency or semitransparency. high tinting strength.

Even though most of the pigment manufacturers use age old process of preparing pigments and then convert them into clay, modern pigments are synthesized in laboratories.
How is pigment used?

What is pigment and where is it used?
Pigments are finely ground natural or synthetic, insoluble particles used to impart color when added to paints and coatings formulations. They are also used to impart bulk or a desired physical and chemical property to the wet or dry film. Some of the main pigment classes include: Organic pigments.
What is pigment in acrylic paint?
Pigment – pigments are granular solids which give paint its color. They are milled to a tiny particle size and do not dissolve, but remain suspended in the paint. Pigments can be organic, inorganic, natural and synthetic. They have little or no affinity for the surface to which they are applied.

Is paint a pigment or dye?
Pigments, like mud, are finely ground particles of color that are suspended in a medium (such as water) to create a paint or coloring agent. Dyes are chemicals, like sugar, that are dissolved in a medium (such as water) to create a paint or coloring agent.

What is a pigment ink?
What is pigment-based ink? A pigment-based ink uses solid particles of pigment powder suspended in the ink itself to transfer colour. This type of ink is more durable than dye-based inks because it resists fading for longer and doesn’t smudge as much when drying.
