we can apply in the colour component by centrifugation aur by chromatography the ink ok it we use has water as a solvent and dye as soluble in it. as the water rises on the filter paper it takes a long with it the dye particles usually a dye is a mixture of two or more colour the coloured component that is more soluble in water rises faster and in this way colours get separated
