Chromatography: A technique to separate pigments based on how far they travel in a solvent.

Rf Value: Distance travelled by pigment / Distance travelled by solvent. Unique for each pigment-solvent combination.

Solvent Front: The leading edge of the solvent moving up the paper.

Origin: The pencil line where samples are initially placed.

Pigments: Different colours separate because they have different affinities for the solvent.
