Can we separate primary colours by chromatography?

Yes, primary colors can be separated by chromatography, a technique that exploits differences in the movement of substances through a medium. When a mixture of primary color pigments is applied to a chromatography medium and a solvent is allowed to travel through it, the pigments will move at different rates based on their affinity for the medium and the solvent. This results in the separation of colors, allowing for the individual primary colors to be identified and analyzed.
