Tetramethyl (four methyls) is known as methyl violet 2B. Solid samples appear blue-green in color; melting is at 137 °C (279 °F). It is used as a pH indicator, with a range between 0 and 1.6. The protonated form (found in acidic conditions) is yellow, turning blue-violet above pH levels of 1.6. = 1.6)

Methyl Violet will transition from yellow (pH 0.2) to violet (pH 2.0).
