A white crystal.
Rock salt (impure salt) is frequently colored.
They are invisible when in an unsaturated, aqueous solution.
Salt appears as small, white crystals or granules, while water is clear and colorless. When salt is dissolved in water, the solution appears transparent but may have a slight cloudy or milky appearance if the salt concentration is high.
Generally the appearance is that of a dusty substance, the colour changes depending on the acidity of the solution when it was in its liquid form and if an indicator was used, usually it is white and dusty. :)
For example melting and boiling of salt are physical processes.

Salt dissolved in water has no appearance. Take a glass of water, sprinkle a little salt in it, stir. Salt disappears when dissolved.

The mixture of salt and water would be transparent because salt crystals would dissolve in water making no difference in appearance.

Yes, table salt is often bleached during the manufacturing process to remove impurities and improve its appearance.
