When could color change be a result of a physical change?
A color change is only a chemical change if the change is permanent, if the color change is not permanent, then it is likely a physical change. Let's look at Iodine for example (that's pronounced Eye-oh-deen), it is a solid metal that is grayish in color in its solid state, however in its gas state it's a purple or violet color. Once it reverts to its solid state, it turns gray again. This is a PHYSICAL property of Iodine. If the color changed permanently to something else, it would be a chemical change.
