Etymology

Chromatographical comes from the Greek root chroma meaning 'colour' and -graphy meaning 'writing', so it originally meant 'colour writing'. A helpful image is colours moving across paper and leaving bands that show the different parts of a mixture, which is why chromatographical describes methods that separate a mixture into its parts.
