Answer:

As water rises on the filter paper, it takes the more soluble colours with it on the top and the less soluble colours are carried up later.

Explanation: in the process of chromatography the coloured spot rises on the paper strip as it is soluble in water and thus due to their solubility the spot rises up .

Chromatography is the technique used for separation of those solutes that dissolve in the same solvent. The ink that we use has water as the solvent and the dye is soluble in it. Hence, this method can be used to seperate dye from black ink.
