A coloured substance can only act as a dye if its molecules can stick to the molecules of the material. This is called mordancy, and depends on the chemical groups present on the molecules of the coloured substance and on the molecules of the material. Think of it as a lock and a key, the key has to be the right shape to fit into the lock.
