Tropaeolin OO (554-73-4)
tropaeolin IV OO · tropaeolin OO, monosodium salt · 4-((4-(phenylamino)phenyl)azo)benzenesulfonic acid monosodium salt
Triphenylmethane, or triphenyl methane, is the hydrocarbon with the formula (C6H5)3CH. This colorless solid is soluble in nonpolar organic solvents and not in water. Triphenylmethane is the basic skeleton of many synthetic dyes called triarylmethane dyes, many of them are pH indicators, and some display fluorescence.
Acid orange 24 (1320-07-6)
Tropaeolin O (547-57-9)
AO6 dye · Acid Orange 6
Chrysoine resorcinol is a synthetic azo dye which was formerly used as a food additive. In Europe, it was banned as a food additive in 1977. In the US, it was banned in 1988.

aniline blue · water blue
Pinacyanol chloride (2768-90-3)
pinacyanol · quinaldine blue iodide · quinaldine blue tosylate
Leucomalachite green (129-73-7)
Malachite green is an organic compound that is used as a dyestuff and controversially as an antimicrobial in aquaculture. Malachite green is traditionally used as a dye for materials such as silk, leather, and paper. Despite its name the dye is not prepared from the mineral malachite, and the name just comes from the similarity of color.
rhodamine 6G cation (63022-06-0, 63022-07-1, 989-38-8, 47724-48-1, 12224-98-5)
rhodamine 6G · basic red 1 · rhodamine 6GO
Rhodamine 6G is a highly fluorescent rhodamine family dye. It is often used as a tracer dye within water to determine the rate and direction of flow and transport. Rhodamine dyes fluoresce and can thus be detected easily and inexpensively with instruments called fluorometers.
Solvent Blue 36 (14233-37-5)
1,4-bis(isopropylamino)anthraquinone · Oil Blue A
Oil Blue A is a blue anthraquinone dye used for colouring certain plastics such as polystyrene and acrylic resins, as well as other materials such as petroleum and inks. It has good resistance to light.

Bromothymol blue (76-59-5)
Bromthymol Blue · Dibromothymolsulfonphthalein
Bromothymol blue (also known as bromothymol sulfone phthalein and BTB) is a pH indicator. It is mostly used in applications that require measuring substances that would have a relatively neutral pH (near 7). A common use is for measuring the presence of carbonic acid in a liquid.
