dye

dye in which the chromophore is part of a negative ion

any of various yellow dyes; not related chemically to alizarin but applied in the same manner

a blue dye obtained from plants or made synthetically

any of many dyes made from aniline

any dye containing one or more azo groups

a dye that is considered to be a base because the chromophore is part of a positive ion

used to whiten laundry or hair or give it a bluish tinge

a dye used as an acid-base indicator

a dye used as an acid-base indicator

a red dyestuff consisting of dried bodies of female cochineal insects

any of a class of dyes containing a -CH= group linking two heterocyclic rings containing nitrogen; used as sensitizers in photography

dye with a high affinity for cellulose fibers (cotton or rayon etc.)

a yellow dye that is visible even when highly diluted; used as an absorption indicator when silver nitrate solution is added to sodium chloride in order to precipitate silver chloride (turns pink when no chloride ions are left in solution and negative fluorescein ions are then absorbed)

any of various fluorescent substances used in fluorescence microscopy to stain specimens

a dye or tint for the hair

a green dye, often used to color cloth, which is obtained from the woad plant

scarlet dye like cochineal; extracted with alkali from stick lac

a poisonous white solid (Pb[CH3CO]2) used in dyeing cotton and in making enamels and varnishes

a purplish dye obtained from orchil lichens

a yellow dye made from the bark of the quercitron oak tree

dye that does not allow the passage of X rays or other radiation; used to outline certain organs during X-ray examination

any of a class of chiefly red organic dyes

a red-purple to deep purple dye obtained from snails or made synthetically

a water-insoluble dye that is applied by reducing the dye to an alkaline form, applying the dye, then regenerating the insoluble dye by oxidation in the material; used for dyeing cotton

a blue dyestuff obtained from the woad plant

acid dye in which the negative ion contains a chelated metal atom

a red-brown azo dye especially as a chemical pH indicator (congo red is red in basic and blue in acidic solutions)

an azo dye used as an acid-base indicator; used for titrations involving weak bases

a red fluorescent dye resulting from the action of bromine on fluorescein; used in cosmetics and as a biological stain for studying cell structures

a fluorochrome commonly conjugated with antibodies for use in indirect immunofluorescence

a reddish brown dye used especially on hair

a liquid preparation used on wet hair to give it a tint

a purplish red water-soluble dye used in microscopy
