Alteration of colour by modifiers

Without any methyl groups the parent dye is called Pararosanilin and is red.

When four methyl groups are added we get the reddish purple dye Methyl violet.

As more methyl groups are added we get the purple blue dye Crystal violet which has six such groups.

If a seventh methyl group is added, the resulting dye is Methyl green.
