hey mate!!!
Iodine is a dark purpley-black solid at room temperature.
It is purple in a hydrocarbon solvent.
It is yellowish-brown in water
The dependence of the colour of iodine solutions upon the nature of the solvent is generally believed to be due to the presence of loosely bound iodine-solvent complexes, or 'solvates', in the brown solutions (for example, in ethanol) and of 'unsolvated' diatomic iodine molecules in the violetsolutions. a solvation serve to account for the marked difference in chemical properties between the violet and brown solutions
And
Iodide ions are colourless, so for example a solution of sodium iodide is colourless. Iodide solutions will only be coloured if the positive counterion were to be coloured.
