Pigments or dyes that absorb light rather than reflect it back to the eye " look black ".

Pigments are used by plants to absorb or detect light, and are extracted by humans for use in dyes.

Pigments are solid, opaque particles suspended in ink to provide color.

Pigments are granular solids incorporated in the paint to contribute color.

Pigments are categorized as either inorganic ( mineral ) or organic ( synthetic ).

Pigments that are not permanent are called fugitive.

Pigments are used for coloring paint, ink, plastic, fabric, cosmetics, food and other materials.

Pigments appear the colors they are because they selectively reflect and absorb certain wavelengths of visible light.

Pigments, diluted in water, are applied to the still wet plaster.

Pigments from the " Bradshaw paintings " of the Kimberley are so old they have become part of the rock itself, making carbon dating impossible.

In 1953, the year that Rohm and Haas developed the first acrylic emulsions, Jose L. Gutierrez produced Politec Acrylic Artists Colors in Mexico and Permanent Pigments Co of Cincinnati Ohio produced Liquitex colors.

Pigments can be classified as either natural or synthetic types.

Pigments, unlike fluorescent or phosphorescent substances, can only subtract wavelengths from the source light, never add new ones.

Pigments and paint grinding equipment believed to be between 350, 000 and 400, 000 years old have been reported in a cave at Twin Rivers, near Lusaka, Zambia.

Pigments from unusual sources such as botanical materials, animal waste, insects, and mollusks were harvested and traded over long distances.

Pigments produced from the cochineal insect gave the Catholic cardinals their vibrant robes and the English " Redcoats " their distinctive uniforms.

Pigments based on minerals and clays often bore the name of the city or region where they were mined.

Pigments used include red and yellow ochre, hematite, manganese oxide and charcoal.

Pigments in paints and stains protect against UV damage.

Poirot has dark hair, which he dyes later in life ( though many of his screen incarnations are portrayed as bald or balding ), and green eyes that are repeatedly described as shining " like a cat's " when he is struck by a clever idea.

Such colors are orders of magnitude more intense than ordinary absorptions seen in dyes and the like that involve individual electrons and their energy states.

One result of these experiments was to reinstate indigo dyeing as a practical industry and generally to renew the use of those vegetable dyes, like madder, which had been driven almost out of use by the anilines.

The discovery in 1856 of mauveine, the first aniline dye, was a forerunner for the development of hundreds of synthetic dyes and pigments like azo and diazo compounds which are the source of wide spectrum of colors.

Many standard fluorescent dyes like GFP, Alexa dyes, Atto dyes, Cy2 / Cy3 and fluorescein molecules can be used for localization microscopy, provided certain photo-physical conditions are present.

Often the tip of the electrode is filled with various kinds of dyes like Lucifer yellow to fill the cells recorded from, for later confirmation of their morphology under a microscope.

This contact with " the philosophy of the ancients " ( as Greek philosophy was often referred to by Muslim scholars ) had a profound effect on his intellectual development, and led him to write hundreds of original treatises of his own on a range of subjects ranging from metaphysics, ethics, logic and psychology, to medicine, pharmacology, mathematics, astronomy, astrology and optics, and further afield to more practical topics like perfumes, swords, jewels, glass, dyes, zoology, tides, mirrors, meteorology and earthquakes.

These dyes are typically sold in punk-themed stores ( such as comic book and music stores ), with brand names like " Beyond The Zone ", " Splat ", ' Fudge Paintbox ' ' Crazy Colors ' " Clairol Jazzing ", " Manic Panic ", " Special Effects ", " Punky Colour ", " Stargazer ", " La Riche Directions ".

Cheminformatics can also be applied to data analysis for various industries like paper and pulp, dyes and such allied industries.

The dog-whelk can be used to produce red-purple and violet dyes, like its Mediterranean relations the spiny dye-murex Bolinus brandaris, the banded dye-murex Hexaplex trunculus and the rock-shell Stramonita haemastoma which provided the red-purple and violet colours that the Ancient World valued so highly.

These films work like any other C-41 film ; development causes dyes to form in the emulsion.

Single molecule detection of normal blinking fluorescent dyes like Green fluorescent protein ( GFP ) can be achieved by using a further development of SPDM the so-called SPDMphymod technology which makes it possible to detect and count two different fluorescent molecule types at the molecular level ( this technology is referred to as 2CLM, 2 Color Localization Microscopy ).

Red dyes are usually added, resulting in its " red diesel " name in countries like the United Kingdom.

The dyes absorbs light much like chlorophyll does in plants.

Reactive dyes are most commonly used in dyeing of cellulose like cotton or flax, but also wool is dyeable with reactive dyes.

It is replacing more traditional Q-switching materials like lithium fluoride and organic dyes.

In textiles, acid dyes are effective on protein fibers, i. e. animal hair fibers like wool, alpaca and mohair.

Antioxidants, like DABCO, are used to improve the lifetime of dyes.

To get back at Jackie, Fez dyes her hair green, and says that now she is ugly on the outside like she is on the inside.

One result of these experiments was to reinstate indigo dyeing as a practical industry, and generally to renew the use of those vegetable dyes, like madder, which had been driven almost out of use by the anilines.
