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
