Iodine in its natural form is of the colour brown. it turns bluish black when starch is added to it. Also, if iodine is added to any solvent that contains oxygen (acetone, ethanol etc), the solution turns brown. On the other hand, if it is added to a solvent that is devoid of oxygen, the solution becomes violet.

Color of iodine solution depends up on the solvent. For example, if we dissolves the iodine in water (which contain oxygen) solution turns brown in color. On the other hand,(without oxygen) solution turns blue in color.
