The hydrated form of copper(II) sulfate is blue in color, whereas the anhydrous form is a very light blue.

Explanation:

In the following video, a sample of copper(II) sulfate heptahydrate is heated to remove the water and produce anhydrous copper(II) sulfate, which is a very light blue color. Then water is added back to form the hydrated form again.
