The first synthetic, organic type of these substances was discovered when aniline was oxidized using potassium dichromate; that compound is called mauveine. Another one of these substances was used to develop the "classical" model of DNA intercalators, and is a derivative of acrindine. Types of these substances called safranin and crystal violet are used to determine the chemical properties of bacterial cell walls in a process named for Christian Gram. For 10 points, name these chemicals that are used to color their targets.
