basic green 4 · (4-(4-(dimethylamino) alpha-phenylbenzylidene)-2,5- cyclohexadien-1-ylidene)dimethylammonium chloride · C.I. 42000
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.
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.

INDIGO (68651-46-7, 482-89-3)
Indigo Blue · Indigo Carmine · indigotin
Indigo is a deep and rich color close to the color wheel blue (a primary color in the RGB color space), as well as to some variants of ultramarine. It is traditionally regarded as a color in the visible spectrum, as well as one of the seven colors of the rainbow: the color between blue and violet; however, sources differ as to its actual position in the electromagnetic spectrum. The color indigo is named after the indigo dye derived from the plant Indigofera tinctoria and related species.

Indigo carmine (860-22-0)
indigo · Indigo Blue · indigotin
Indigo carmine, or 5,5′-indigodisulfonic acid sodium salt, is an organic salt derived from indigo by sulfonation, which renders the compound soluble in water. It is approved for use as a food colorant in the U.S and E.U., It has the E number E132. It is also a pH indicator.
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.

Disperse Orange 1 (2581-69-3)
Disperse Orange 1 (4-anilino-4'-nitroazobenzene) is a dye of the azobenzene class. Disperse Orange 1 contains approximately 25% dye by weight, with the remaining mass consisting of NaCl and other salts. This dye is useful in conducting experiments with flash photolysis due to the isomerization effect between the trans-4A4N and cis-4A4N states that occurs during photo relaxation.
