What did the different colored bands signify in each solvent for Part 1?

In Part 1 of the chromatography experiment, the different colored bands represent the separation of the components of the ink based on their solubility in the solvent. Each band corresponds to a different component of the ink, with the distance traveled by each band reflecting its solubility and interaction with the solvent used. The separation of the bands allows for the identification and analysis of the different components present in the ink sample.
