Remarks:
Azure, a methylated thiazine dye, is a metachromatic basic dye indicator which is resulting and ranging from green (to chromosomes) and blue (to nucleoli and cytoplasmic ribosomes), to red colour (to deposits containing mucopolysaccharides). There are many methylated homologues used as components of many polychrome stains in combination with eosin and methylene blue in pH adjusted solutions.
