Using bromothymol blue you wouldn't be able to distinquish between an acid with pH 4 from an acid with pH 5. They would both appear yellow. Similarly solutions with pH 9 and pH 10 would both appear blue (vivid blue). With bromothymol blue you could hope to identify solutions with pH 6.5 (yellowish green), pH 7 (green) and, and pH 7.5 (bluish

It is known in medicine as Gentian violet (or crystal violet or pyoctanin (e)) and is the active ingredient in a Gram stain, used to classify bacteria. It is used as a pH indicator, with a range between 0 and 1.6. At a pH of +1.0, the dye is green with absorption maxima at 420 nm and 620 nm, while in a strongly acidic solution (pH −1.0), the dye is yellow with an absorption maximum at 420 nm.
